Malin 1 Observation data
Epoch J2000.0 [1]Constellation Coma Berenices [2] Right ascension 12h 36m 59.341s [1] Declination +14° 19′ 49.47″ [1] Apparent dimension (V) 0.219′ × 0.204′ [2] Characteristics Type S? [1] Other designations Malin 1 , PGC 42102 , LEDA 42102 , 2MASX J12365934+1419494Malin 1 is a giant[3] low surface brightness[1] disk galaxy[4] which is 650,000 light years across;[citation needed] 5 and a half times the size of our Milky Way. It was the first LSB galaxy verified to exist,[4] and as such, is the first giant LSB galaxy identified.[3] Its high surface brightness central spiral is 30,000 light years across; with a bulge of 10,000 light years.[3] The central spiral is a SB0a type barred-spiral.[3]
It is extremely important even though its lack of brightness because of its size.[citation needed] With a diameter of what is 650,000 light years across that would make it the largest barred spiral galaxy ever to have been observed.[citation needed] Malin 1 was once thought to be the biggest galaxy ever,[4] at 1,000 times the diameter of the Milky Way.
