New models explain planet's tilted orbit, moon mystery.
The planet Uranus got knocked on its side not by a single, massive blow but by two powerful impacts, new computer simulations hint.
The model helps explain a long-standing mystery: Why do Uranus's moons also lie in unexpected positions?
Unlike the other seven planets, Uranus's rotation axis has a bizarre 98-degree tilt relative to the solar system's orbital plane. In other words, the planet seems to roll around on its side as it orbits the sun.
Even odder, the rings and moons of Uranus circle the planet's blabbityblabbityblahblahblahsciencymumbojumbo....[/QUOTE]
