The '''Andromeda Galaxy''', also known as '''M31,''' or '''NGC 224''' is a large barred [[spiral galaxy]] (type Sb), the nearest one to the [[Milky Way]], and situated within the same [[galactic cluster]] called the [[Local Group]]. It appears to be within the constellation [[Andromeda (constellation)|Andromeda]], hence its name.

Located beyond the Milky Way, the Andromeda galaxy is one of the most distant objects visible to the unaided eye in the night sky.  The galaxy is the largest of the Local Group with perhaps as many as one trillion stars to the Milky Way's 200-400 billion stars.<ref>http://www.newscientist.com/article/dn9282-andromeda-galaxy-hosts-a-trillion-stars.html</ref>  Once thought to be the most massive galaxy as well, more recent studies have shown our galaxy is at least as massive.<ref>http://www.cfa.harvard.edu/news/2009/pr200903.html</ref>
