NGC 5008 (also known as IC 4381 ) is a massive barred spiral galaxy located in the Boötes constellation.[1]
Details
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 light-years, NGC 5008 easily dwarfs the Milky Way and is considered one of the largest galaxies .[3] According to the SIMBAD Database, NGC 5008 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
The four galaxies of Hickson compact group 71.
NGC 5008 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 away compared to the other galaxies.[6]
