What is the dwarf elliptical galaxy shooter?

elliptical galaxy Sagittarius is the third closest neighboring galaxy of the milk galaxy where our solar system is located. In just 50,000 light years away from the core of the Milky Way, the shooter galaxy is involved in the polar orbit around the Milky Way, which slowly absorbs it. Even now, the shooter galaxy leaks the star stream, a fiber that stretches around the core of the Milky Way like the Gossamer loop. The shooter's galaxy is named after the constellation where it can be found, a shooter.

Discovered in 1994 has only about 10,000 light -years in the elliptical galaxy of the shooter compared to the Milky Railway diameter of 100,000 light years. The Milky Way galaxy is estimated to be about 10,000 times more massive than the shooter galaxy. Until 2003, it was assumed that he was the closest galaxy of the Milky Way, although this place recently captured the main dwarf Galaxy Canis, which is also absorbed by the Milky Way. Both galaxies, along with about eight others, are considered the satellites of the dairy galaxy dRahy.

The shooter galaxy has about a billion stars compared to 200-400 billion Milky Way stars. Although it occupies a part of the sky -like sky, the shooter galaxy is very weak, because most of them are covered with a galactic disk. His central star cluster, M54, was discovered only in 1778 by Charles Messier, making him the first extragalactic stars, even though he realized the community of astronomy for more than two centuries.

elliptical galaxy Sagittarius is one of the few galaxies to be on a direct collision course with the Milky Way. It will go through a galactic disk for about a hundred million years. But because the galaxies themselves are very scattered, it will hardly increase your stellar collisions.
