its a spiral galaxy and the earth is so far the only planet in the milky way where we know we can live
That would be the Milky Way Galaxy.
A spiral galaxy
The word galaxy is a noun used to describe a cluster of billions of stars. One way to use the word in a sentence would be to say, "The Milky Way is the galaxy of stars that we live in."
I believe that would be M31.
We are in the Milky Way galaxy.
It wouldn't matter where the Sun was, the Milky Way Galaxy would still have a diameter of around 100,000 light years.
The Canis Major Dwarf Galaxy is currently considered to be the closest galaxy to the Milky Way. It is 25,000 light years from our solar system and 42,000 light years from the center of the Milky Way. Its status as a galaxy is still disputed in some scientific circles. If the Canis Major Dwarf Galaxy loses its galaxy status, then the Sagittarius Dwarf Spheroidal Galaxy would reacquire the title as the Milky Way's closest neighbor. It is it is roughly 50,000 light years from the center of the Milky Way.
I believe that would be M31.
Our spiral galaxy of The Milky Way Galaxy is approximately 80,000 to 120,000 light-years across, and less than 7,000 light-years thick.
34.8 billion miles would still be in our galaxy, the Milky Way.
Without the Milky Way Galaxy, in which our solar system exists, we would not be here.
All stars that are named are within the Milky Way galaxy.The closest star would probably be in the Canis Major Dwarfgalaxy, our nearest galaxy.
