NGC 4070 is an elliptical galaxy located 340 million light-years away ^[2] in the constellation Coma Berenices. ^[3] NGC 4070 was discovered by astronomer William Herschel on April 27, 1785. It was rediscovered by John Herschel on April 29, 1832 and was listed as NGC 4059. ^[4] The galaxy is a member of the NGC 4065 Group. ^{[5] [6] [7] [8] [9] [10] [11]}

NGC 4070 is also classified as a LINER galaxy. ^[12]

Physical characteristics

Deep images obtained with the CAFOS instrument at the Calar Alto Observatory reveal that NGC 4070 has some deviation from a perfectly spherical or ellipsoidal shape morphology. This indicates that NGC 4070 has undergone a recent interaction, either with the galaxy 2MASX J12040831+2023280 or with a small knot of material. There also appears to be a faint, broad bridge of luminous matter between NGC 4070 and the neighbouring elliptical galaxy NGC 4066. The two galaxies are separated by a projected distance of 370,000  ly (114  kpc ). ^[13]

SN 2005bl

On April 14, 2005 a type Ia supernova designated as SN 2005bl was discovered in NGC 4070. ^{[13] [14] [15] [16] [17]}
