DETAILS NGC5813 is an elliptical, classed as a LINER galaxy while NGC5814 is a spiral. The two are separated by some 400 million light years. In fact SDSS J150059.36+013857.1 is much closer, so much so that it can be considered an interacting galaxy with NGC5813 and most probably a dwarf galaxy. SDSS J150121.96+014401.2 is a Quasi stellar object, barely visible in this image. The other 2 objects arrowed (B and C) are galaxies
