The angles for Earth, Uranus, and Venus are approximately 23°, 97°, and 177° respectively. In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, which is the line perpendicular to its orbital plane; equivalently, it is the angle between its equatorial plane and orbital plane ...
Uranus has an axial tilt of 97.77°, so its axis of rotation is approximately parallel with the plane of the Solar System. The reason for Uranus's unusual axial tilt is not known with certainty, but the usual speculation is that it was caused by a collision with an Earth-sized protoplanet during the formation of the Solar System.

Voyager ' s observations revealed that Uranus's magnetic field is peculiar, both because it does not originate from its geometric centre, and because it is tilted at 59° from the axis of rotation. [ 135 ] [ 136 ] In fact, the magnetic dipole is shifted from Uranus's centre towards the south rotational pole by as much as one-third of the ...
Its unusual tilt makes Uranus appear to orbit the sun like a rolling ball. Uranus, which orbits almost 20 times further from the sun than Earth does, has 28 known moons and two sets of rings.

NASA’s Voyager 2 flyby in 1986 provided the only close-up look at Uranus. Nearly 40 years later, scientists are looking back at this data and finding out the visit happened during a strange ...
The orbits of the regular moons are nearly coplanar with Uranus's equator, which is tilted 97.77° to its orbit. Uranus's irregular moons have elliptical and strongly inclined (mostly retrograde) orbits at large distances from the planet. [3] William Herschel discovered the first two moons, Titania and Oberon, in 1787.
