On their own axes, Uranus and Saturn both rotate retrogradely, counterclockwise. Only a small percentage of the planets’ known satellites exhibit retrograde motion. The four outermost moons of Jupiter are among them.

How many planets rotate in the reverse direction?
Our planet, like the majority of other planets, rotates in a retrograde motion. However, only two planets, Venus and Uranus, rotate around the sun (retrograde motion).
We should all be aware by now of the fundamentals of our solar system, such as the existence of eight planets and their axis rotation in addition to their orbital motion around the sun.
But did you know that there are a few oddball planets in our solar system that rotate in the opposite way from Earth and most other planets?
larger impact on the opposite side of the planet, which caused it to rotate in the opposite direction, causing the satellite it had previously created to spiral in and collide with the planet.
Those are Venus. Since Uranus doesn’t rotate normally in either a clockwise or counterclockwise manner, it is highly unusual. Venus must have been booted by someone to cause it to roll on its side if it were rotating backwards. The majority of planetary axes are parallel to the plane of the orbit. Uranus, however, has a pole that is directed toward the equatorial plane of the other planets and a highly inclined axis of 97.7o.
The planet’s dramatic seasons are caused by its high tilt, and its polar days are out of the ordinary. Uranus has typical days and nights at the equator. However, because it spins on its side, one pole or the other is always more or less pointing toward the Sun. As a result, 42 Earth years of day and 42 Earth years of darkness are experienced at one pole. The South Pole is under darkness when the North Pole is facing the Sun, and vice versa.
How could this have occurred, then? Same as with Venus, Uranus also had counterclockwise rotation until a massive impact changed everything. The explanation for this is that in its formation history, Uranus collided with an Earth-sized object which caused to the alteration of its spin.
Another theory and simulation without collision by Gwenael Boue and Jacques Laskar from Paris Observatory suggests that Uranus had very massive moon with 0,1 percent of Uranus’s mass. The gravitational interaction between the two caused Uranus’s axis to tilt the way it is currently. And for the moon itself, it was thrown from the system when they encountered other big planets.

Are there any planets in retrograde motion?
What planet is moving backwards? The solar system is continuing to be active after a little pause. This winter’s nearly three-month period of calmness. But in late April, the 2022 Pluto retrograde sent everything spinning (backwards).
Venus does it revolve backwards?
In 1962, radar was able to break through the clouds and measure the planet’s rotational cycle. Venus rotates once every 243.0185 Earth days, whereas the Earth rotates once every one Earth day. If seen from the north pole, the planet revolves in a clockwise direction. The west is where the sun rises. It is known as a retrograde rotation (backwards compared to the Earth and most other planets).
Is there a retrograde rotation on Mars?
Comparable to race vehicles on an oval circuit are the two planets. Earth is in the inside lane and travels more quickly than Mars; in fact, it completes two laps of the track in roughly the same amount of time as Mars does one.
Earth catches up to Mars and passes it once every 26 months. This year, as we pass by the red planet, it will appear to us as though Mars is rising and falling. The illusion will eventually vanish as we continue along our curved orbit and view the planet from a different angle, allowing us to once more see Mars moving straight ahead.
Retrograde motion is the term for this seemingly irregular motion. Jupiter and the other planets that orbit the sun further away also experience the illusion.
The orbits that Earth and Mars follow don’t precisely lay on the same plane, which just adds to the strangeness of the situation. It appears as though the two planets are traveling down distinct tracks that are just slightly off-center from one another. This results in yet another odd illusion.
Imagine you could mark the location of Mars on a sky map every night as it moves forward, goes into retrograde, and then resumes its forward motion. You can either draw an open zigzag or a loop by connecting the dots. Depending on where Earth and Mars are in their skewed racetrack orbits, a certain pattern will emerge.
Is there a retrograde motion on Mars?
Let’s apply that to Mars right now. Mars appears to alter its course in the sky every two years and spend a few months moving backward. Beginning on June 28, 2018, Mars’ retrograde motion appeared to move from west to east in our sky until August 28 before resuming its usual course.
However, Earth is acting differently over those two months, not Mars.
Why do Venus and Uranus rotate counterclockwise?
I’m here. I’m looking for a list of the DIRECTIONS in which planets rotate, particularly in this solar system. We much appreciate any help.
Except for Venus and Uranus, every planet in our solar system spins from west to east when viewed from above the North Pole. All of the planets orbit the sun in the same way. Early in its history, Uranus was probably struck by a very big planetoid, causing it to rotate “on its side,” or 90 degrees away from its orbital motion. Venus rotates counterclockwise to the other planets, which is also probably a result of an early asteroid collision that altered its initial rotation.
What is the only planet with a clockwise rotation?
The majority of the solar system’s celestial bodies, including the Sun, planets, and asteroids, rotate anticlockwise.
This is because of the early circumstances in the gas and dust cloud that gave rise to our solar system.
This gas and dust cloud started rotating as it started to disperse.
It just so happened that the rotation was counterclockwise.
However, a counter-clockwise rotation is nothing exceptional.
If the initial state of rotation of the gas and dust cloud from which our solar system arose was clockwise, we might have easily found ourselves inhabiting a solar system that rotated around our Sun in that direction.
But keep in mind that our solar system contains two outliers that revolve differently from the other planets.
Venus revolves about its axis counterclockwise, while Uranus rotates about an axis that is almost parallel to its orbital plane (i.e., on its side).
These anomalies are assumed to be the result of occurrences like collisions that took place during the solar system’s creation.
Does Uranus rotate counterclockwise?
On Uranus, a day lasts roughly 17 hours (the time it takes for Uranus to rotate or spin once). And it takes Uranus roughly 84 Earth years to complete one orbit of the Sun, or one year in Uranian time (30,687 Earth days).
With a tilt of 97.77 degrees, Uranus is the only planet whose equator is almost at a right angle to its orbit, probably as a result of a collision with an Earth-sized object in the past. The most intense seasons in the solar system are brought on by this peculiar tilt. The Sun shines directly over each pole for over a quarter of every Uranian year, sending the other half of the planet into a 21-year-long, gloomy winter.
Additionally, just two planetsUranus and Venusrotate from east to west, the opposite direction from the majority of the planets.
In which retrograde are we currently in 2021?
Again, Mercury is in retrograde. In astrology, Mercury is the planet that primarily governs communication. Mercury entered retrograde motion on September 27, 2021, and it will remain in that state through October 18, 2021. Mercury looks to be moving backward from west to east while it is in retrograde.
