- TL;DR Summary
- Was Uranus in a tussle with Neptune and Planet 9?
Now, Uranus seems to have had an eventful early life. According to theory, it got hit by a large planetary body, which knocked it's axis to nearly 90°. Also according to another theory, it apparently had a close encounter with Neptune which took Neptune further away, when initially it was closer than Uranus.
I'm wondering if maybe the two events were related, and possibly the same event? I'm also wondering if a third body was involved in this, let's say the hypothetical Planet 9? What if at one point Planet 9 and Uranus got into a very close orbit with each other, such that they were basically a dual-planet system for a little while. Then Neptune tried to come into the mix, and it ended up knocking Planet 9 out into a huge orbit, and ended up skewing Uranus' rotation axis, as Planet 9 went flying off?
