It's a dwarf galaxy; the diameter is about 6500 light-years (according to information in the Wikipedia article).
The Milky Way is estimated to be about 2,000 light years thick, but about 100,000 light years long/far... Which i guess you can tell, thats a lot.
Somewhere around 26,000 light-years.
Answer: 100,000 light years = 9.454e+17 km
ESO 510-G13 is a spiral galaxy approximately 150 million light-years away in the constellation Hydra See:- http://en.wikipedia.org/wiki/File:Warped_galaxy.jpg
8 billion light years means that the light has taken 8 billion years to reach you. That's how far into the past you are seeing.
100,000 ly across but only about 1000 ly thick.
The Milky Way galaxy is approximately 100,000 light-years (30 kiloparsecs, 9x1017 km) in diameter, and is considered to be, on average, about 1,000 ly (0.3 kpc) thick .
The nearest galaxy to our Milky Way is the Andromeda galaxy, which is about 2.5 million light years away (that is not including the Large and Small Magellanic Clouds, small, irregular "satellite" galaxies of our own).
The Andromeda Galaxy is a separate galaxy, about 120,000 light years across, containing trillions of stars - possibly many with planets. Our Solar System is a single star with 8 planets and at best measures 2 light years.
The Andromeda Galaxy is at a distance of about 2.5 million light-years from Earth; or from the Milky Way.

23 million light-years.

2.5 million light-years approximately ;)
its about 2.5 million light years away
The Milky Way galaxy is around 100 thousand light-years across from end to end. (A light-year is the distance light travels in a year through the vacuum of space, equal to just under 10 trillion kilometres). It contains around 100 billion stars, many of which are thought to have solar systems of their own.
