Uranus spins on its side — unlike any other planets and moons in the solar system — is this a stable spin or will it eventually selfright as a spinning top, and how long would that take ?
In: Physics
The top rights itself because of the interaction between the top and whatever it’s spinning on, and that interaction only occurs because there is a universal “downward” force of gravity. The solar system has no such objective preference for which direction is “down,” thus there’s not much reason to suggest Uranus will ever match the other planets. Granted, there *might* be some interaction between Uranus and everything else in the solar system (via gravity) that kinda-sorta rights Uranus, but it would be an extremely slow process that would take *much* longer than the presumed lifespan of our solar system.
