It's about 2000 light years thick
Yea We are in the center of the milky way
The Milky Way spiral galaxy is about 100,000 light years in diameter, and about 3,000 light years thick at its center, and about 1,000 light years thick near its outer edge.
No
I'm assuming your not an intergalactic, extraterrestrial and that your galaxy is the same as my galaxy - the Milky Way. There is overwhelming evidence that a super-massive black hole is at the center of the Milky Way.
Center or whole? 0 miles if it's the whole galaxy because Earth is IN the Milky Way Galaxy but IDK center.
The milky way
The Earth is located in a galaxy called the Milky Way. It is about 26,000 light-years from the center.
We cannot see the center of the Milky Way galaxy, because it is hidden by clouds of interstellar gas. However, there is reason to believe that there are no stars at the center of the Milky Way, but only a supermassive black hole.
Our Milky Way galaxy has a center that is thick with stars, and then a number of spiral arms like curved octopus arms. Earth is located about 3/4 of the way out on one of these arms.
Earth is about 26,000 light-years from the center of the Milky Way.
Most astrophysicists believe that there is a supermassive black hole at the center of the Milky Way.
our galaxy contains between 200- to 400-billion stars arranged in a giant disc shape. The diameter is 100,000 light years with an average thickness of 10,000 light years. The Earth is located about 28,000 light years from the center of the Milky Way.
