Each individual object (such as a star) revolves around the galactic center according to the laws of celestial mechanics. As a result, the objects closer to the center of the galaxy take less time for a complete revolution than the objects further out; the galaxy rotation is differential, meaning it does not rotate as if it were a solid object.
Rotation of picture
The Sun, all its planets and the galaxy in which the Sun sits all rotate.
Yes, in fact everything in the universe rotates.
Obviously. All galaxies must rotate - otherwise, they would collapse due to their own gravity.
It does. It rotates about its axis and revolves around the galaxy.
The Milky Way galaxy is in a local group of 30 or more galaxies of which M30 or Andromeda and the Milkyway are the most massive and they center to a point somewhere between each other. Each have their own satelite galaxies that rotate with the major spiral dominant galaxy
No. If a galaxy were not to rotate, it would soon collapse upon itself, due to its own gravitation.
About 220 km/sec.
Yes it really does! It rotates around the Milky Way Galaxy.
There aren't really any other names for a galaxy that I can think of, but there are galaxy classifications, such as spiral galaxies (that can rotate either clockwise or counter-clockwise), elliptical galaxies, and irregular galaxies.
none of those. milky way is a part of the galaxy and our solar system is a part of it. in this solar system the planets revolve around the sun and rotate on thier own axis
Yes. The Sun in turn orbits the galaxy. Planets and the Sun also rotate on their axes.
