Uranus is Weird

Back 1986, Voyager 2 flew by the planet Uranus and gave us our only set of closeup data so far. Recently, that flyby data has shown us the Uranus is even stranger than we thought.

The planet’s rotational axis is tipped over almost 90 degrees, and the Voyager data has revealed that its magnetic axis points about 60 degrees away from the rotational axis. The planet’s magnetosphere wobbles around, and to date, no one has come up with a reasonable explanation of for the odd offset.
