Did the planet uranus have pole shift or somthing?
Why Uranus has the axial tilt it does isn’t known with any certainty. A magnetic pole shift couldn’t cause such a thing. In order for a magnetic field to perform work it requires some other magnetic field or permeable material with which to react and Uranus has no such properties. As far as a collision with some other object — Uranus has 26 known moons (and counting). The outer 8 are all over 4 million km from the planet, are small, move in retrograde orbits that are highly inclined (i.e. 140-170 degrees), and quite elliptical, all of which indicates that they are captured asteroids (or KBOs, or Centaurs), so we can ignore them. The inner 18 are all within .5 million km of the planet, are of varying sizes, but are all in almost perfectly circular orbits that are right on Uranus’s equator. Every single one of them has less inclination to Uranus’s equator than our moon does to ours, and a less eccentric orbit than our moon has. They undoubtedly were formed at the same time as Uranus. A
