What is the accepted theory as to why Uranus' axis is tilted so severely?
Nasa.gov speculates that
the most likely possibility is that an object with a mass close to that of Earth's collided with Uranus, causing it to rotate on its side from then on.
A recent test by Space.com suggests that &quot;Planet Uranus Got Sideways Tilt From Multiple Impacts&quot;. These findings suggest that two or more smaller collisions probably occurred, asserting that the early solar system was probably more turbulent than most would think.
