There are a number of theories for this, but one of the most popular is that it was hit by a large planetary object which knocked to spin that way.
Actually there are two, Venus and Uranus.
It rotates in opposite (retrograde) direction from other planets
That would be Venus which rotates retrograde. Actually, Uranus does too.
Venus (and also Uranus) rotates in the opposite direction to most other planets.
Uranus. Its spin is tilted 90 degrees to that of all the other planets.
You probably mean Venus, but Uranus is the other one.
It rotates on its axis at a 90 degree angle to the sun.
This is known as prograde rotation, all of the planets spin in this direction apart from Venus and Uranus. Venus and Uranus spin clockwise when viewed from above the north pole, this is known as a retrograde spin.
Venus and Uranus both do this. Venus is the clearest example.
All planets orbit the sun in the direction that the sun is rotating. There are actually two planets that rotate by retrograde motion and are exceptions to this rule. These planets are Venus and Uranus.
Yes, Venus rotates in the opposite direction to most other planets, a phenomenon known as retrograde rotation. Uranus rotates on its side, with an axis tilt of about 98 degrees. These are exceptions to the general rule that planets rotate with small axis tilts and in the same direction as their orbit around the Sun.
Retrograde rotation is when a planet rotates in a direction opposite to the majority of planets in our solar system. The planet Venus rotates in retrograde, meaning it spins clockwise on its axis when viewed from above its north pole. This is in contrast to the counterclockwise rotation of most planets, including Earth.
