Uranus that rotates on its side takes 17 hours and 14 minutes (Earth Time).
Uranus. 17h 14m 24s for one spin on its axis.
Uranus spin is different from all the other planets. Instead of spinning like a top, it spins like a wheel. Its north and south poles stick out to the side. Scientists think Uranus spins this way because a long time ago a large object collided with Uranus and knocked it over.
14.24 hours Even though Uranus is a much larger planet than earth, it spins faster because most of the planet is made of gas (smaller solid core can spin faster).
If you look at the entire solar system, all the planets, except Uranus, rotate in the same direction. If you call north up, then all planets rotate on that axis except for Uranus. Uranus spins on it's side in this model. While all the other planets spin on the North/South axis, Uranus spins on the East/West axis.
Uranus is sometimes referred to as the "sideways planet" because it spins on an axis that is tilted almost 98 degrees
"Horizontal" isn't really the correct "scientific" way to describe it, but the answer is Uranus.
Venus and Uranus are the two planets that spin backwards compared to the majority of the planets in our solar system. Venus rotates in the opposite direction to its orbit around the Sun, while Uranus is tilted on its side, causing its rotational axis to be nearly parallel to its orbit.
Most of the planets in our solar system spin anticlockwise (counterclockwise) when viewed from above the north pole, but Uranus and Venus are exceptions - they spin clockwise on their axis.
The planet Uranus spins on its side.
Uranus rotates on its axis in a retrograde direction, or clockwise when viewed from above the Sun's North Pole. This unique rotation may have been caused by a powerful impact that tipped the planet on its side early in its formation. The tilt of Uranus' axis is so extreme that it leads to extreme variations in sunlight exposure and seasonal changes on the planet.
The planet Uranus has an rotational axis of 97.77°.
