Being one of the few constellations that resembles its namesake, Leo is a well-known constellation. The Big Dipper’s “pointer stars,” which point to Leo, make it rather simple to locate.
March does really arrive like a lion. Around the spring equinox, the constellation becomes visible in the Northern Hemisphere, and it is simple to identify through May. Leo is situated halfway between Virgo and Cancer.

When is the best time to see the constellation Leo?
Star patterns called constellations create fictitious images in the sky. The International Astronomical Union has given official names to 88 constellations. On both sides of the globe, they fill the entire sky, and many of them are the subject of tales and stories from all over the world.
Only specific times of the year can you see particular constellations. Leo is a fantastic constellation to spot in the northern hemisphere’s springtime night sky, especially around April and May.
Leo is visible for the majority of the night after emerging in the early evening. Leo will stop visible in the evening sky by late July or early August and won’t reappear until late September or early October, just before dawn.
Where is the constellation Leo visible?
At 947 square degrees, Leo is the 12th-largest constellation in terms of size. It can be visible from latitudes between +90 and -65 in the northern hemisphere’s second quadrant (NQ2). Cancer, Coma Berenices, Crater, Hydra, Leo Minor, Lynx, Sextans, Ursa Major, and Virgo are the nearby constellations.
Messier 65 (M65, NGC 3623), Messier 66 (M66, NGC 3627), Messier 95 (M95, NGC 3351), Messier 96 (M96, NGC 3368), and Messier 105 are among the five Messier objects in Leo (M105, NGC 3379). 11 of its stars have identified planets.
Along with Aries, Taurus, Gemini, Cancer, Virgo, Libra, Scorpius, Sagittarius, Capricornus, Aquarius, and Pisces, Leo is a member of the Zodiac family of constellations.
Regulus, Alpha Leonis, the brightest star in Leo, has an apparent magnitude of 1.35.
One of the fifteen equatorial constellations is Leo. There are 13 identified stars there. The International Astronomical Union (IAU) has officially authorized the names Adhafera, Algieba, Alterf, Chertan, Denebola, Dingolay, Formosa, Moriah, Rasalas, Regulus, Sagarmatha, Subra, and Zosma for stars.
The constellation is connected to two meteor showers. The Leonids typically reach their annual peak on November 1718 and have a radiant close to the brilliant star Gamma Leonis. A brief shower called the January Leonids peaks between January 1 and January 7.
When will the star Leo be visible?
Leo is easy to spot in the spring because it is virtually always visible in the sky in the months of March, April, and May. The stars that make up the lion’s face and front legs form a pattern like a backwards question mark, making the constellation simple to spot.
Where in the sky is Leo right now?
One of the 13 zodiac constellations with the best visibility is Leo the lion. Start by locating the prominent star Regulus, then locate The Sickle, a peculiar collection of stars that resembles a backwards question mark. The Lion’s mane is represented by this design. In Greek mythology, Leo stood in for the ferocious Nemean Lion that Heracles, the heroic hero of Greece, slew.
From the perspective of the Northern Hemisphere, the Lion appears in the early evening sky around the March equinox and is a fair-weather companion.
Leo the Lion can be seen as soon as night falls and is visible until the early hours of the morning, making late March, April, and May excellent months for this task. Keep in mind that you’re looking for a pattern of reversed question marks. The brightest star in Leo, Regulus, is a brilliant blue-white beauty that may be found at the base of the shape of a reversed question mark. Regulus shows the heart of the lion.
The lion’s hindquarters and tail are represented by a triangle of stars in eastern Leo. Denebola, an Arabic word that means the Lion’s Tail, is the name of the triangle’s brightest star.
Like other stars, those in Leo rise and set in the same location in the sky at intervals of around four minutes each day or about two hours per month. Around 10 p.m. local time (11 p.m. local daylight saving time) in early April, the constellation Leo reaches its highest peak for the night and begins to set below the western horizon (5 a.m. local daylight saving time). Leo reaches its peak for the night at 8 p.m. local time around about May 1. (9 p.m. local daylight saving time). Also in early May, at around 2 a.m. local time, the majestic Lion starts to set in the west (3 a.m. daylight saving time). By June, Leo will be descending in the west at dusk.
Even while Leo moves steadily westward in the early evening sky over the course of the months, the Lion can still be seen until July. The Lion starts to disappear into the distance by late July or early August. The sun will be in front of Leo from around August 10 through September 16. In late September or October, the constellation makes a comeback to the eastern morning sky.
Leo the Lion is always visible if you are familiar with the Big Dipper star pattern or asterism. The Big Dipper in March appears to be standing on its handle in the northeastern sky at dusk. When it gets dark in April, look higher in the northeast sky for the Big Dipper, and when it gets dark in May, look higher in the north, above Polaris, the North Star, for the almost-upside-down Big Dipper. Then, locate the Big Dipper’s two pointer stars, or the two outside stars in the bowl of the constellation. The North Star, Polaris, is indicated by a line drawn between these stars that extends northward. The line points toward the stars in Leo in the other direction.
To gain a sense of the telescopic riches that are contained within the borders of this constellation, look at the chart above.
When the atmosphere is stable, a tiny telescope can see the double star Algieba or Leonis. A tumultuous, rather than a stable, environment is indicated by the stars’ erratic twinkling. On the other hand, if the stars are hardly flashing or not at all, try your luck using a telescope to separate Algieba, which seems to the unaided eye to be a single star, into its two bright component stars.
M65 and M66, a pair of closely related galaxies in Leo, also offer a tempting focus for the telescope. You might be able to view both M65 and M66 in one field of view with a low-powered telescope.
The sun has traditionally been linked to Leo the Lion. The ancient Egyptians held Leo in the highest esteem, because the sun shone in front of this constellation during the time of the annual flooding of the Nile River, the lifeblood of this agricultural nation.
It is believed that the numerous fountains with lion heads created by Greek and Roman architects represent the life-giving waters produced by the sun’s position in Leo.
Leo, one of the three fire signs of the Zodiac, is the sun’s sign.
Leo the Lion is a character in many tales. The first labor of Heracles (also known as Hercules) with the infamous Nemean Lion and the Roman author Ovid’s depiction of the tragic love story between Pyramus and Thisbe are arguably the two more well-known stories.
In conclusion, Leo the Lion begins to show in the evening sky in late March and is one of the easiest zodiacal constellations to locate. It is linked to Greek mythology’s Nemean lion.
Does Leo appear in December?
Leo constellation is visible from October to May, however around April it can be seen high in the sky at 21:00:
- From February in the eastern sky through July in the western sky, early evening observers (before 21:00) can see the constellation. In April, the constellation Leo will be visible in the sky.
- From January in the east until June in the west, observers can spot the constellation throughout the middle of the evening (21:00-23:30). In March, the constellation Leo will be visible in the sky.
- From November in the eastern sky through May in the western sky, late-evening observers (after 23:30) can see the constellation. In January, Leo will be visible in the sky.
- From September in the eastern sky through February in the western sky, early-morning observers can spot the constellation. In December, Leo will be visible in the sky.
The constellation will gradually get brighter as time goes on, and the ranges below show when you can see it each month. The Leo constellation is located 10 to 25 degrees north of the equator. As a result, it will seem more north in the sky the farther south you are. Leo is seen in latitudes between +90 and -60 at its maximum range.
In the Southern Hemisphere, can you see Leo?
Leo is the third largest of the 12 zodiacal constellations, behind Virgo and Aquarius, with an extent of 947 square degrees. It is immediately recognized as the majestic lion it represents, and the “Sickle,” a cluster of six stars that resembles a backwards question mark, is one of the night sky’s most spectacular asterisms, second only to the Big Dipper.
Location: A Northern Constellation
Leo is an easy constellation to see if you follow the Big Dipper’s “pointer stars” away from Polaris to an area where Leo may be located between Gemini and Cancer to the west and Virgo to the east. Leo is a northern sky constellation visible to observers between latitudes +90 and -65 degrees. Other adjacent constellations include Coma Berenices, which is made up of stars from the lion’s “tail,” Hydra, which is directly above Leo, and Leo Minor, which is above Leo.
Best Seen: Spring
Leo is a winter constellation that may be seen from January to June in the northern hemisphere, but it becomes more prominent in March, just before the spring equinox. Leo is seen in the southern hemisphere in the summer and fall.
Notable Stars: Regulus (1st magnitude)
Four stars in the constellation of Leo are first- or second-magnitude, making it stand out in the night sky. These stars include Algieba, Regulus, and Deneb:
With an apparent visual magnitude of 1.35, Regulus (Alpha Leonis), a multiple system around 77 light years away, is the brightest star in Leo and the 22nd brightest star in the entire night sky. Regulus is actually two binary systems orbiting each other, with Regulus A, a blue-white main-sequence star (B7V), as the primary system. Regulus A orbits a possible white dwarf 0.35 AU away once every 40 days or so.
The other system is made up of Regulus B, an orange dwarf (K1-2 V), and Regulus C, a red dwarf (M5 V), which are separated from the main pair by 100 AU and have an orbital period of 2,000 years. They are both located 4,200 AU from the main pair. Regulus, the “Small King, which means “little king” in Latin, is one of the stars used to calculate longitude since it is visible for eight months out of the year and almost exactly coincides with the ecliptic.
The second brightest star in the constellation, Algieba (Gamma Leonis), is a binary system 130 light years away from our solar system with a magnitude of 2.28. Its main star, K1-IIIbCN-0.5, is an orange giant that is 23 times larger and at least 180 times brighter than the Sun. Its fainter companion, G7IIICN-I, is a yellow giant that is 10 times larger and about 50 times as bright. A planet has been found orbiting the main component, and the duo orbit one another roughly every 500 years. Although the star truly denotes the lion’s mane, the Arabic word algieba means “the forehead.”
The third brightest star in Leo, Denebola (Beta Leonis), is a blue main sequence dwarf (A3 Va) that can be found 36 light years away and shines with a visual magnitude of 2.14. It is about 200 million years old, 1.75 times bigger, and 12 times brighter than the Sun. The Arabic word for “Tail of the Lion” is the source of the name Denebola.
Other Leo stars worth noting include Al Minliar al Asad, Chertan, Ras Elased Australis, Subra, and Zosma (“Hip of the Lion,” “Head of the Lion,” and “The Rib,” respectively) ” (“Muzzle of the Lion). Wolf 359, a red dwarf star that is one of the nearest stars to Earth at a distance of just 7.78 light years, is another star in the constellation. Being only 8% of the mass of our Sun and around the same size as Jupiter, it is also as small as a real, blazing star can get.
Notable Objects: Many Bright Galaxies
An astonishing number of deep-sky objects (DSOs) that may be seen using a telescope can be found in the constellation Leo, including 5 Messier objects: the spiral galaxies M65, M66, M95, M96, and the elliptical galaxy M105. NGC 3628, NGC 3607, NGC 3593, NGC 3384, NGC 3842, NGC 3596, NGC 2903, NGC 3626, and NGC 3357 are only a few of the several additional galaxies in Leo.
At a distance of around 35 million light years, Messier 65 (M65, NGC 3623), an intermediate spiral galaxy, has an apparent visual magnitude of 10.25. As a result of the lack of significant star formation in this galaxy due to the lack of gas and dust, the vast majority of its stars are extremely ancient.
Another intermediate spiral galaxy, Messier 66 (M66, NGC 3627), is located 95 thousand light-years away and is 36 million light-years away. It has four known supernovae and an apparent visual magnitude of 8.9.
Approximately 38 million light years away, Messier 95 (M95, NGC 3331) is a barred spiral galaxy with an apparent visual brightness of 11.4. M96, M105, and at least nine additional galaxies of diverse kinds make up the M96 Group, which also includes M95. The 2,000 light-year-diameter ring-shaped starburst zone that surrounds the galaxy’s core and the fact that a supernova was discovered there in March 2012 make M95 stand out.
Contains 2nd Biggest Structure in Universe
Leo also houses the Huge-LQG, the second-most enormous astronomical structure yet found in the universe (large quasar group). This vast region is made up of 73 quasars that are dispersed over 4 billion light-years of space. Our Milky Way is only 100,000 light-years across in contrast. The Hercules-Corona Borealis Great Wall, which is 10 billion light-years wide, is the only object larger than the Huge-LQG.
Meteor Showers: The Leonids (+3 others)
There are several meteor showers that occur in the constellation Leo, with the following peak dates: the Delta Leonid (end of February), Sigma Leonid (April 17), Leonids (Nov 17), and Leo Minorids (Dec 14).
The Leonids, which are the year’s most impressive meteor displays, are connected to the comet Tempel-Tuttle and are Leo’s most frequent meteor shower. From November 13 to November 21, it is visible, reaching its peak on November 17 when 20 or more meteors can be observed every hour. The next one is anticipated to occur in 2032, however on average, thousands of meteors can be seen every hour once every 33 years. The largest one is thought to have happened in 1833; estimates put the count at between 100,000 and 240,000 per hourright, that’s up to 4,000 every minute, 67 per secondfor the nine hours it dumped meteors. When there were no interior or outdoor lights, the scene in a famous piece of art representing the 1833 shower is lit almost as brightly as during the day.

Star Lore: Leo and the Nile River
One fascinating bit of star history goes as follows, despite the fact that it is unclear how the ancient Egyptians first learned about the constellation Leo. Because they were aware that the Sun entered the constellation during the Flooding of the Nile, which provided copious amounts of water and rich soil to the area, the ancient Egyptians worshiped Leo. This yearly natural cycle, which also happened to coincide with the arrival of desert lions at the river, was essential to Egypt’s ability to secure its food supply. Although the lions at that time moved toward the river to escape the heat and scarcity of water in the desert, the Egyptians saw a connection and honored the lion with festivals. Even today, numerous lion statues can be found along the Nile River’s course as evidence of how highly the ancient Egyptians regarded desert lions.
What time of year can you see Orion?
From November through February, Orion can be seen in the night sky (opens in new tab). The quickest way to find the Orion Constellation is to locate Orion’s Belt. Alnilam, Mintaka, and Alnitak are the three brilliant stars that make up Orion’s Belt.
What makes the constellation Leo unique?
Leo is one of the largest zodiac constellations in the night sky. Deep-space objects and brilliant stars are everywhere. There are also several Messier objects in this area. The constellation of Leo also contains some asterisms.
In September, which constellation is prominent?
The constellations Capricornus, Cygnus, Delphinus, Equuleus, Indus, Microscopium, and Vulpecula are the ones that are easiest to see in September. Northern constellations include Cygnus, Delphinus, Vulpecula, and Equuleus, while southern constellations include Capricornus, Microscopium, and Indus.
The ideal time of year to examine several fascinating deep sky objects found in these constellations is around September. The North America Nebula (NGC 7000), Crescent Nebula (NGC 6888), Blinking Planetary Nebula (NGC 6826), and Fireworks Galaxy are some of the most well-known telescope sights (NGC 6946).
The Swan is symbolized by Cygnus, the northernmost of the September constellations. The Northern Cross, which is made up of the stars Deneb (Alpha Cygni), Sadr (Gamma Cygni), Albireo (Beta Cygni), Fawaris (Delta Cygni), and Aljanah, dominates the constellation and makes it very easy to recognize (Epsilon Cygni).
Is Leo in the northern horizon?
They directly point at the North Star (Polaris), which also happens to be the first star in the Little Dipper’s handle, if you follow them to the North. Leo will be seen if you follow the pointer stars to the south.
