NGC-3109 Spiral galaxy in Hydra

NGC-3109

NGC-3109 is a small, irregular spiral galaxy located in the constellation of Hydra. Although its actual size is relatively small, because of its distance of only 4 million light years it appears relatively large in the sky, with an angular size of 19 by 4 minutes of arc. It contains only 230 million stars, and has relatively low surface brightness.
