UGC 477[3] is a low surface brightness (LSB) galaxy, located in the Pisces constellation. It is located over 110 million light years away.[5] At around 100,000 light years across, it is similar in size to the Milky Way galaxy.[4] The earliest known reference to this galaxy comes from part 2 of the Morphological Catalogue of Galaxies, published in 1964, where it is listed as MCG +03-03-002.

According to I.D. Karachentsev, UGC 477 forms an isolated galaxy pair with NGC 251.[6]
