What planet rotates bottom to top?
No such planet that we know of rotates any way other than horizontally or vertically on an axis.
That would be Uranus, it is almost laying on its side, as it faces the Sun. Earth faces the sun standing almost straight up, with the north and south poles at the top and bottom. Uranus, however, has its south pole facing the Sun. Also, the planet rotates, or spins, from east to west which is the exact opposite of the way that Earth spins.
