NGC 5910 is an elliptical galaxy[3][2][4] located about 540 million light-years away[3] in the constellation Serpens. It was discovered by astronomer William Hershel on April 13, 1785.[4] NGC 5910 is also a strong radio source[5][6] with a conspicuous nuclear jet.[7]

Physical characteristics

NGC 5910 appears to have a double nucleus,[6] with a faint nuclear dust lane also being observed.[7]

A pair of asymmetries in the isotopotal profile of NGC 5910 with one of them being brighter than the other, weaker asymmetry suggests a past merger and collision of one or more galaxies.[8]

Group membership

NGC 5910 is the brightest[2] and dominant[8] member of a compact group of galaxies known as Hickson Compact Group 74.[8] The group consists of 5 members in total,[5][9] with a velocity dispersion of 537 km/s and a diameter of 260,000 ly (80 kpc).[10] The other members are 2MASX J15193179+2053005, PGC 54692, PGC 54694, and MCG+04-36-036. [9] The other galaxies appear to be embedded within a common envelope that belongs to NGC 5910.[6]

NGC 5910 appears to lie near the Hercules Superclusters.[11]
