UGC 4599 is a low luminosity elliptical-like ring galaxy that is known for being the nearest galaxy of its type to Earth at 26.9 mpc. It superficially resemble a Hoags Object in sky imaging surveys.[1][2] Because of this, it has often been called Hoag-like or a Hoag analog.[3]

The galaxy likely appeared to be the shape it is today due to a major interacting between two galaxies at least 5 billion years ago.[1]

Morphology

The center of the galaxy is nearly round and reddish. A luminous dominate blue ring surrounds the galaxy that is composed of a one-and-a-half turn spiral feature.[3] On side of the spiral has star formation active in the form of nine detected Hii regions.[1]
