The galaxy was discovered in 1987 by Sanduleak and Pesch, and is located at a distance of about {{Convert|45.7|Mpc|ly}} in the Boötes Void and has no significant neighbours within 2.5 Mpc.

The galaxy may be a counterpart to the rectangular-shaped galaxy LEDA 74886, in that they both appear to contain an intermediate-scale disk. In the case of LEDA 74886, that disk is orientated edge-on to our line-of-sight. The "early-type galaxy" class is commonly known to contain

elliptical galaxies (E) with no substantial stellar disk (perhaps just a small nuclear disk) and lenticular galaxies (S0) with their large-scale disks that dominate the light at large radii. Bridging these two types of galaxies are the ES galaxiesLiller, M.H. (1966), [http://adsabs.harvard.edu/abs/1966ApJ...146...28L The Distribution of Intensity in Elliptical Galaxies of the Virgo Cluster.
