Uranus orbital plane?

Question

why doesn't Uranus orbital plane tilt as much as other planets(except earth)

Answer 1

Or why does Mercury tilt more? I don't know. All the planets have slightly different tilts, but they are all within a few degrees of each other. So the difference is probably just random chance in how they formed and have interacted with each other gravitationally ever since.

Answer 2

Uranus' orbit is tilted only by 43'23'' of arc (roughly 3/4 of a degree), but others are tilted much more with Mercury at 7d and Pluto (not a planet) at 17d.

The unique feature of Uranus is its (rotational) axial tilt of about a right angle (97.92 degrees), making it lie in the plane of ecliptic unlike for others, nearly perpendicular to ecliptic.

Answer 3

Even a scientist studying our solar system would tell you that it's still a fascinating mystery.

Answer 4

it is the way it was flung and spun, and the angle it was spun, the energy, magnitude force, inertia. like a top you spin it straight or you can spin it crooked.

Answer 5

Uranus's orbital plane is only tilted less than .8degree

This happened at the time of formation of solar system.

Answer 6

The orbital plane of all the planets is entirely a random phenomenon set by the initial conditions within the nebula in which our solar system formed.

Answer 7

There is no absolute frame of reference for obliquity of an orbit.  We use the plane of the earth's orbit as a convenient starting point.  That having been said, some planets are close to that plane and some are slightly inclined to it.  Being nearly coplanar is what would be expected, as the planets formed from a relatively flat accretion disk in the beginning of the solar system.
