Question

What is the name of the closest galaxy and how far away is this galaxy?

Answer

The closest galaxy to Earth (apart from our own galaxy, the Milky Way) is called the Canis Major Dwarf Galaxy, and it is about 25,000 light-years away from Earth. The Canis Major Dwarf contains about 1 billion stars and is actually located WITHIN the Milky Way (galaxies are not always entirely separate). The closest galaxy that is NOT a part of the Milky Way is called Andromeda. It,s about 2,500,000 light-years from Earth and contains around 1 trillion stars. Scientists predict that about 4 billion years from now, Andromeda and the Milky Way will collide and form a super galaxy!
