Messier 109 (also known as NGC 3992) is a barred spiral galaxy approximately 83.5 ± 24 million light-years away in the constellation Ursa Major. M109 can be seen southeast of the star Phecda (γ UMa).
In March 1956, supernova 1956A was observed in M109. SN 1956A was a type Ia supernova in the southeast part of the galaxy, glowing at magnitude 12.8 to 12.3 at its maximum. SN 1956A has been the only supernova observed in M109 since its discovery. It is also by far the most distant object in the Messier Catalog, followed by M91. M109 has three satellite galaxies and possibly might have more.
