PGC 29820 (known as JO204) is a spiral galaxy located 600 million light-years away from the Solar System in the Sextans constellation.[1] The galaxy is about 120,000 light-years in diameter and is a member of Abell 957, a low-mass galaxy cluster.[2] The first known reference to this galaxy is from volume I of the Catalogue of Galaxies and of Clusters of Galaxies compiled by Fritz Zwicky in 1961, where it was listed as CGCG 008-077.[3]
