Uranus is the celestial black sheep of our small cosmic family. Most of the solar system's planets rotate counterclockwise when viewed from above and have vertical poles that are aligned with the sun's. Not Uranus. The planet's poles are tilted 98 degrees and it spins clockwise. ...
by astronomer Clyde W. Tombaugh. The existence of this planet was actually proposed years before by American Percival Lowell, who had theorized that slight disturbances in the orbits of Uranus and Neptune were caused by the gravitational pull of another planet. Lowell even went so far as to mak...
How is the rotation of Uranus different from other planets? Why is Mercury the closest planet to the sun? Why aren't planets on the planisphere? Why is Neptune an outer planet? Why do planets orbit in ellipses? Is the Northern Hemisphere tilted toward or away from ...
