Because of the movement of the stars and other observable stellar object's.
The Sun, or the Solar System, rotates AROUND the galaxy. After 230 million years (or whatever time it takes - you should understand that's an estimate), it will return, more or less, to the position it is now.
We know the Sun rotates because we can watch sunspots on the face of the Sun.
An electron.
The sun actually rotates so it does move.
The Milky Way doesn't really rotate around anything. Our home galaxy and nearby Andromeda are pretty much at the center of what is called a local group of gravitationally bound galaxies. As such, it is unsupportable to say that the Milky Way rotates around anything else.
Yes, in fact everything in the universe rotates.
It does. It rotates about its axis and revolves around the galaxy.
Yes it really does! It rotates around the Milky Way Galaxy.
The Sun partakes in the general rotation of the galaxy (the Milky Way Galaxy rotates once about every 225 million years). This corresponds to an average velocity of about 220 km/s.
Aside from occupying space, our galaxy also rotates. It takes about 220 million years for it to spin once.
What about it? General info: The milkyway galaxy is a spiral galaxy that rotates around a center of mass believed to be a black hole. On December 21st 2012 it is predicted that the earth will be in line with this center of mass

no in the galaxy no .....but it the universe no body know
We know the Sun rotates because we can watch sunspots on the face of the Sun.
We know the Sun rotates because we can observe stationary sun spots moving across its surface.
there is no v shaped galaxy that I know of.
Ummm... I know earth is IN a spiral galaxy called the Milky Way Galaxy
