NGC 3862 is an elliptical galaxy located 300 million light-years away[2] in the constellation Leo.[3] Discovered by astronomer William Herschel on April 27, 1785,[4] NGC 3862 is an outlying member of the Leo Cluster[5] and is the second brightest member after NGC 3842.[6]

The galaxy is classified as a FR I radio galaxy[7] and hosts a supermassive black hole that is blasting a jet of plasma that is moving at 98 percent of the speed of light and is one of the few jets in active galaxies that can be seen in visible light.[8]
