Uranus only planet in the solar system that spins sideways
Uranus is the only planet in the solar system that spins sideways as its equator is nearly at a right angle to its orbit. The tilt possibly occurred due to the planet's collision with an Earth-sized object long ago. Uranus, which is the seventh planet from the Sun, was discovered on March 13, 1781, by British astronomer William Herschel.
