Planets and dwarf planets to scale in size, rotation speed, axial tilt and oblateness, numbered in order of distance from the Sun
Axial tilts for each planet are found by the right-hand rule – if you close your hand and keep your thumb out: the direction of planetary rotation is given by your fingers, while thumb points north. Sidereal days are shown.

The tilts would ordinarily be all upright in a perfect system because dust and gas all orbited the same way in the early solar system. However, impacts by giant asteroids and planetesimals during that time will tend to modify the system, in addition to planetary migration.
Impacts to Uranus have been simulated by scientists here and please stop smirking about this sentence. https://twitter.com/physicsJ/status/1219974650224136192

I like introducing people to Ceres... If you want Pluto, you can't really skip Ceres. It's a dwarf planet in the asteroid belt. There are other dwarf planets beyond Pluto as well
