The galactic disk, which bulges outward at the galactic center, has a diameter of between 70,000 and 100,000 light-years. The distance from the Sun to the galactic center is now estimated at 26,000 ± 1400 light-years, while older estimates could put the Sun as far as 35,000 light-years from the central bulge.
The galactic center harbors a compact object of very large mass (named Sagittarius A*), strongly suspected to be a supermassive black hole. Most galaxies are believed to have a supermassive black hole at their center.
The Galaxy's bar is thought to be about 27,000 light-years long, running through its center at a 44 ± 10 degree angle to the line between the Sun and the center of the Galaxy. It is composed primarily of red stars, believed to be ancient (see red dwarf, red giant). The bar is surrounded by a ring called the "5-kpc ring" that contains a large fraction of the molecular hydrogen present in the Galaxy, as well as most of the Milky Way's star formation activity. Viewed from the Andromeda Galaxy, it would be the brightest feature of our own galaxy

The sun?????? Good grief! At least google it before making a comment like that. There is a difference between solar system and galaxy, there really is. A difference of about 100,000,000,000 stars. And as the previous person said, the center is likely a big ol' black hole.

Although we can't see it, because it is too gravitationally strong to allow the emittance of light, a gigantic star-eating black hole is at the center. This black hole, probably typical, keeps over 99% of its own galaxy from flying apart. Our neighbor galaxy, Andromeda, is closing toward us at 300,000 miles per hour, toward our mutual intersection at which point there will emerge a new center of our two conjoined galaxies. The separation of the two, right now, is approx. two and 1/2 million light years and, as said, closing at 300,000 miles per hour. Cited: ' Universe.'

It is called the Galactic Circle, composed of a supermassive black hole, dense super stellar cluster containing massive stars, and other gases.
Personally, I think we are the center of the galaxy, who else is?
There is a very good link
