IC 4381 (known as NGC 5008) is a massive barred spiral galaxy located in the Boötes constellation.[1]
Details[edit]
It is located 530 million light-years away from the solar system and was discovered by Heinrich d'Arrest, a Prussian astronomer on May 18, 1862 as NGC 5008.[2] It was again discovered on June 15, 1895 by Stephane Javelle who listed it in the Index Catalogue as IC 4381.[2] With a diameter of 400,000 thousand light-years, IC 4381 easily dwarfs the Milky Way and is consider as one of the largest galaxies.[3] According to SIMBAD Database, IC 4381 has a LINER type active galactic nucleus.[4] It has a surface brightness magnitude of 14.07, meaning it is a low-surface brightness galaxy.[5]
Group membership[edit]
IC 4381 is the dominant member of the Hickson Compact group, HCG 71. The other members of the group are IC 4382, PGC 50640 and PGC 50641, which is further compared to the other galaxies.[6]
