NGC 6051 is a giant elliptical galaxy located in the constellation of Serpens. The galaxy lies 453 million light-years from Earth, which means given its apparent dimensions, the galaxy is around 250,000 light-years across.[1] It is the brightest cluster galaxy inside a relaxed poor cluster called AWM 4, a fossil system,[2] making up of at least 30 galaxy members.[3]
