NGC 3607 is a lenticular galaxy located in the constellation Leo. It is part of the Leo I Group and is approximately 55 million light-years away from Earth. NGC 3607 has a bright central bulge and a disk that is less prominent than that of spiral galaxies. This galaxy is notable for its relatively smooth appearance and lack of significant spiral structure. It is often studied for its stellar population and the presence of a supermassive black hole at its center, which is common in many galaxies, including NGC 3608, its nearby companion.
