Interesting . . . the largest planet rotates the fastest.
I wonder why that is.
High angular momentum leads to faster rotation, because faster rotation leads to collisions among particles that cause the gas to settle into a spiral disk, rather than a more spread out cloud.
What is the difference between an elliptical galaxy and a spiral galaxy?
Elliptical galaxies are ellipsoids with no clearly visible internal structure. Spiral galaxies have a very dense nucleus and a region of stars bulging outwards from the disks and, therefore, called the central bulge. Elliptical galaxies also have dense centers, but they do not protrude from the body of the galaxy.
Galaxies rotate, or spin around a central axis, and because of something called density waves, helps galaxies to become spiral in shape.

Answer: east and west
Explanation:The east
to west daily motions of stars, planets, the Moon, and the Sun are caused by the rotation of the Earth on its axis. The Earth and all the planets revolve around the Sun on circular orbits.
