NGC 7623

NGC 7623 is a lenticular galaxy located in the constellation Pegasus. It was discovered on September 26, 1785, by the German-British astronomer William Herschel.
The galaxy is situated at a distance of approximately 160 million light-years from the Milky Way, based on its redshift. NGC 7623 is classified as a lenticular galaxy, exhibiting structural characteristics intermediate between elliptical and spiral galaxies.
NGC 7623 is part of the Pegasus I Group, a nearby galaxy group composed primarily of early-type galaxies. It forms a close pair with the neighboring elliptical galaxy NGC 7626, and the two galaxies are frequently studied together in investigations of galaxy interactions and group dynamics.
Multiwavelength observations, including optical and X-ray studies, suggest the presence of diffuse hot gas associated with the surrounding group environment, consistent with lenticular galaxies located in dense regions.
NGC 7623 is catalogued in several major astronomical databases, including the New General Catalogue, the Uppsala General Catalogue, and the Principal Galaxies Catalogue.
