NGC 4565 (also known as the Needle Galaxy or Caldwell 38) is an edge-on spiral galaxy about 30 to 50 million light-years away in the constellation Coma Berenices. It lies close to the North Galactic Pole and has a visual magnitude of approximately 10. It is known as the Needle Galaxy for its narrow profile, and is a prominent example of an edge-on spiral galaxy. It was discovered by German-British astronomer William Herschel on 6 April 1785.
