Gemini is the 30th largest constellation in the sky, with a 514-square-degree surface area. It can be observed at latitudes between +90 and -60 in the northern hemisphere’s second quadrant (NQ2). Auriga, Cancer, Canis Minor, Lynx, Monoceros, Orion, and Taurus are constellations nearby.
Gemini, along with Aries, Taurus, Cancer, Leo, Virgo, Libra, Scorpius, Sagittarius, Capricornus, Aquarius, and Pisces, is a constellation in the zodiac.
Gemini has a Messier object in the form of the star cluster Messier 35 (NGC 2168) and seven stars with known planets. Pollux, Beta Geminorum, is the brightest star in the constellation, with an apparent brightness of 1.14. The Geminids and the Rho Geminids are two meteor showers linked with the constellation. The Geminids are normally bright and peak around the 13th and 14th of December.
There are ten named stars in Gemini. The International Astronomical Union (IAU) has authorized the star names Alhena, Alzirr, Castor, Jishui, Mebsuta, Mekbuda, Pollux, Propus, Tejat, and Wasat.

What is the zodiac sign of Gemini?
Even for amateur astronomers, Gemini is a rather straightforward constellation to see in the sky. It is situated northeast of the constellation Orion and between the constellations Taurus and Cancer. The best time to visit is in February. By April and May, the constellation can be seen in the west shortly after sunset.
The twins’ heads are represented by the brightest stars in the constellation, which are also named after Greek mythology’s Castor and Pollux, while the twins’ bodies are outlined by fainter stars. According to NASA, Pollux, a red giant star, is 33 light-years away from Earth, whereas Castor is 51 light-years away. (A light-year is the distance traveled by light in one year, which is approximately 6 trillion miles (9.6 trillion kilometers.) Castor has two partner stars, whereas Pollux has at least one huge planet around it.
What is the current location of the constellation Gemini?
Most people only see two bright stars in the constellation Gemini Castor and Pollux, also known as the Gemini twins. These two celebrities aren’t identical twins. The hue of Pollux is brighter and more golden. Castor is a tad lighter and whiter. However, both stars are bright, and their proximity on the sky’s dome makes them stand out. People have imagined they looked like brother stars since the dawn of mankind.
Best viewing for this constellation
The months of January, February, and March are ideal for stargazing. At nightfall, Gemini is high in the east. Gemini reaches its peak point in the sky about 10 p.m. local time in early February. Around 9 p.m. in late February, the constellation is at its brightest. That is local time, or the time on your clock, regardless of where you are on the planet.
Until approximately May, Gemini is visible in the evening sky. Gemini lies low in the west at nightfall by late May and early June, and Gemini’s two brightest stars, Castor and Pollux, vanish into the sunset before the June 21 summer solstice. From roughly June 21 to July 20, the sun passes in front of Gemini once a year.
Myths and lore
Castor and Pollux were the offspring of a mortal mother, Leda, according to legend. Castor, the human son of Tyndareus, and Pollux, the immortal son of Zeus, were brothers. Castor and Pollux were joyously connected in soul, but their lives were torn apart by circumstance. When Castor was killed in battle, Pollux was heartbroken and implored Zeus to free him from his immortality chains. Pollux and Castor are reunited in the sky to this day, a testament to the redeeming power of sibling love, as Zeus accepted his request.
As a result, the Greek tale of Castor and Pollux explores the inherited duality of life, the eternal intertwining of death and immortality.
Here’s how to find Gemini from constellation Orion
If you look into the night sky in February, there’s a strong chance you’ll see the constellation Orion the Hunter. Orion is high in the south on February evenings in the Northern Hemisphere.
The Belt stars of Orion are a short, straight row of three medium-bright stars. Rigel, an extremely bright blue-white star, may be found below Orion’s Belt. Do you see it? Look above Orion’s Belt for Betelgeuse, a reddish star. Do you see what I mean? Castor and Pollux can be found by drawing an imaginary line from Rigel through Betelgeuse. Keep in mind that you’ll want to look for two bright stars that are obviously close together.
Here’s how to find constellation Gemini using the Big Dipper
The Big Dipper is an asterism, or a pattern of stars in the shape of a dipper. It is not a genuine constellation. On the sky’s dome, the Big Dipper is always pointed northward. Draw an imaginary line from the star Megrez to the star Merak diagonally through the bowl of the Big Dipper. You’re heading in the opposite direction of the Big Dipper’s handle. Castor and Pollux will be indicated by this line.
You can also use the moon to find Gemini.
Every month, the moon swings full circle through the zodiac constellations, passing through Gemini for a few days. Check EarthSky Tonight for posts showing the moon near Castor and Pollux on specific days, especially in the months of January, February, and March. The next time it happens will be on April 18 and 19, 2021.
Play around with Stellarium, an online planetarium application. It can tell you when the moon is in Gemini each month (except during those months when Gemini is behind the sun).
Spotting Sirius when Gemini is high in the sky
Gemini and Sirius, the brightest star in the night sky, reach their greatest peaks in the sky around the same time. The brightest stars in Gemini, Castor and Pollux, are practically overhead in middle latitudes in the Northern Hemisphere, while Sirius shines low in our southern sky. The opposite is true south of the equator: Sirius glows brightly while Gemini hangs low in the northern sky.
Bottom line: The greatest seasons to gaze for the constellation Gemini in the night sky are during the winter and spring. The brightest stars in Gemini, Castor and Pollux, are twin brothers from Greek and Roman mythology.
When does Gemini appear?
Gemini is a northern constellation dominated by Castor and Pollux, the two brightest stars. It is visible throughout the northern winter months, peaking around New Year’s Eve at midnight.
The galactic plane and the ecliptic line both pass through this region of the sky: just after the June solstice, the Sun crosses the boundary from Taurus and remains in Gemini until late July.
The name ‘Gemini’ is Latin meaning twins and refers to the Greek gods Castor and Pollux.
Their mother was Leda, but their fathers were different. Castor was the son of Tyndareus, the Spartan ruler, while Pollux was Zeus’ son.
Castor was killed in a family fight with his cousins, but Pollux was an immortal demigod, according to tradition. Following his brother’s death, Zeus offered Pollux the option of sharing his immortality with him, and the two were flung into the sky for all eternity.
Where do I look for Gemini and Orion?
During the first few months of the year, the two brightest stars in Orion (a constellation that resembles a large hour glass) and the two brightest stars in Canis Major and Canis Minor (the “dog” stars) that follow Orion are the easiest to find. Then, around the same distance from the two brightest stars in Orion as the separation between the two brightest stars in Orion, travel northeast. After Capella and a few other stars, Pollux will be among the brightest stars in the sky. Castor and Pollux are then roughly two fingers apart at arm’s length from each other. Following the discovery of these two stars, the rest of the constellation forms a rectangle pointing toward Orion. One intriguing fact is that the two stars that make up Castor and Pollux’s heads, fittingly named Castor and Pollux, have extremely distinct characteristics. Pollux has been getting brighter and brighter for the last thousand years and is now the brightest star in the constellation. Castor is a complex star system made up of six different stars, while Pollux has been getting brighter and brighter for the last thousand years and is now the brightest star in the constellation.
In the Southern Hemisphere, where is the constellation Gemini?
At 12 a.m. on November 6, 2020, the graphic depicts the scene looking east from London. The moon will be three-quarters bright and will appear to be sideways, parallel to the horizon, as it sits right between the twins.
The constellation is one of the 12 zodiac constellations and one of the 48 constellations first reported by Ptolemy in the second century. Its name is derived from the Latin word for twins and refers to the classical mythological half-brothers Castor and Pollux. The constellation’s two brightest stars are named for the siblings.
The constellation is lower in the sky in the southern hemisphere. It will appear near the north-eastern horizon, heads-down.
When is Gemini visible in the Northern Hemisphere?
Gemini, the Twins, is visible from November to April in the Northern Hemisphere and from December to March in the Southern Hemisphere.
What are the characteristics of Geminis?
What are the characteristics of Geminis? People born under the sign of Gemini are intellectual and have expressive looks. Their movements are usually fast and energetic. Because they’re a patchwork of multiple selves sewn together to form a coherent identity, their eyes are usually always two different colors.
Is it possible to tell if the Gemini twins are male or female?
This star pattern, which consists of two nearly parallel lines of stars crowned by two of the brightest stars in the night sky, has been regarded by many cultures as two persons. The tale of Castor and Pollux, on the other hand, lives on. The twins’ names are written on the two brightest stars in Gemini.
The queen of Sparta gave birth to two pairs of twins, one boy and one girl in each pair, according to the most popular account of their narrative. Her husband fathered one pair of children, while Zeus, the gods’ monarch, fathered the other. The four lads one mortal, the other immortal were inseparable as they were raised together. They went on many adventures with Jason and the other Argonauts in search of the golden fleece.
However, the mortal Castor was slain during a confrontation with some landowners. Pollux was distraught and begged Zeus to let him die so that he might join Castor. Zeus consented to keep Pollux and his brother together for all eternity after being moved by Pollux’s affection for his brother. They spend half of their time in the underworld and the other half in the heavens, where the stars of Gemini represent them.
Pollux is the more brilliant of the two twins. The star is around 35 light-years away from Earth. The star is orbited by at least one planet. It has a mass at least three times that of Jupiter and orbits Pollux every 1.6 years.
Castor has a total of six stars. This dense system is roughly 50 light-years away from Earth. Because they were created from a single massive cloud of gas and dust some 200 million years ago, all six stars in the system are truly connected.
Castor’s twins are more fraternal than identical in two pairs. Each pair of stars has one star that is larger, brighter, and heavier than the Sun, while the other star is smaller, fainter, and less massive. Each of these sets of stars is so close together that they orbit each other in a few of days. Telescopes can’t see them as distinct stars since they’re so close together. Instead, special instruments separate the stars’ “fingerprints” as they orbit each other, revealing information about each one.
The third set of Castor twins is the same as the first. Each star is much fainter, smaller, cooler, and less massive than the Sun. And, whereas the other two sets of twins are relatively close, these “twins” are so far apart that orbiting the others takes thousands of years.
What does the constellation Gemini look like in the sky?
Stargazers can find Gemini’s feet in the Milky Way on moonless evenings or in areas with little light pollution. Pollux (yellow-orange) and Castor (bluish-white), the twins’ brightest stars, designate their heads. They are only 5 degrees apart, making them an excellent celestial yardstick. At New York’s Hayden Planetarium, there was a very popular lecturer in the 1940s and ’50s named Henry Neely who would point to Pollux and Castor and then down to a third bright star named Alhena, which marks one of Gemini’s feet. Neely would connect these three stars with the “Wedge of Gemini,” a much easier pattern for modern stargazers to find. “Somehow or another, the ancient stargazers managed to detect in these stars the shapes of two heroes standing close together,” Neely would tell his audience.
“However,” he continued, “it is futile for us to attempt to reproduce this feat of visualization.”
Even still, it’s not as dismal as Neely would have us believe. H.A. Rey transforms Gemini into a convincing framework in his classic book “The Stars – A New Way to See Them” (Houghton Mifflin Co., 1952), in which he depicts the Twins as two matchstick men holding hands. After its publication in 1952, Rey’s novel became highly successful. He also lived in New York, and I wondered if he ever attempted to meet Neely in person to correct him.
From March through June, which constellation is most visible in the sky?
The Swan, Cygnus, is one of the most well-known summer constellations. Its brightest stars form the Northern Cross asterism, which is visible in the evening sky throughout the summer months. The Swan’s tail is marked by Deneb, the brightest star in the constellation and one of the brightest northern stars. It’s one of the brightest northern stars, as well as the most distant first magnitude star, at 3,550 light years from Earth.
A variety of other noteworthy stars can be found in Cygnus. Albireo, Beta Cygni, is a binary system with distinct colors that is popular among amateur astronomers. It is frequently referred to as the “beak star” since it marks the Swan’s head. The Swan’s chest is marked by Sadr, Gamma Cygni, who sits at the heart of the Northern Cross. A diffuse nebula known as IC 1318, also known as the Sadr region, surrounds the star (Gamma Cygni region).
The X-ray source Cygnus X-1, the bright open clusters Messier 29 and Messier 39, the Fireworks Galaxy, and several prominent nebulae such as the Pelican Nebula, Crescent Nebula, and Veil Nebula may all be found in Cygnus.
Lyra, a minor constellation between Cygnus, Hercules, and Draco that is easily identified by its parallelogram shape, is home to Vega, the fifth brightest star in the sky, as well as two other well-known stars. Sheliak, Beta Lyrae, is the prototype for the Beta Lyrae variables, a class of binary stars so close together that material from one star flows into the other, causing the stars to become egg-shaped. The Double Double, also known as Epsilon Lyrae, is made up of two pairs of binary stars orbiting each other. The system, which is located near Vega, is a popular target for amateur astronomers.
The globular cluster Messier 56, the famed Ring Nebula (Messier 57), the trio of merging galaxies designated as NGC 6745, and the open cluster NGC 6791 are the best known deep sky objects in Lyra.
A cluster of stars known as the Keystone forms an asterism next to Vega. Hercules is the constellation in which these stars are found.
There are no first or second magnitude stars in Hercules, the sixth largest constellation in the sky. Because several of its stars form the Keystone, a renowned July asterism that symbolizes Hercules’ torso, it’s simple to spot. Hercules standing on the head of the mythical Ladon, the dragon he defeated as part of his 12 labors, is a common depiction of the constellation. The Draco constellation, which is close by, represents the dragon.
The brilliant, huge Hercules Globular Cluster (Messier 13) and the slightly dimmer, denser, and smaller Messier 92, one of the Milky Way’s earliest known clusters, are both found in Hercules. The Hercules Cluster of galaxies, with roughly 200 known members, the interacting pair of galaxies Arp 272 (NGC 6050 and IC 1179), and the active galaxy Hercules A are all found in the constellation.
Corona Borealis, a minor constellation formed like a horseshoe or tiara, is located on the other side of the Keystone, between Hercules and Botes. The minor constellations Sagitta, the Arrow, and Vulpecula, the Little Fox, are connected by an imaginary line stretched from Altair into the middle of the Summer Triangle. Outside the Summer Triangle, Delphinus, a minor constellation with a readily recognized form, can also be seen near Altair.
During the summer, the zodiac constellations Sagittarius and Scorpius can be seen above the southern horizon. One of the most conspicuous constellations in the southern sky is Sagittarius. The brightest stars create an asterism known as the Teapot, which makes it easier to spot. The constellation, which is located on the Milky Way, is home to a number of prominent deep sky objects. The Sagittarius Dwarf Elliptical Galaxy, Barnard’s Galaxy, the Quintuplet Cluster, the Pistol Nebula with the luminous Pistol Star, the Arches Cluster, and a total of 15 Messier objects, including the Lagoon Nebula (M8), the Trifid Nebula (M20), the Omega Nebula (M17), the Sagittarius Star Cloud (M24), and the Sagittarius Cluster (M22).
