NGC 4261 is an elliptical galaxy located behind the Virgo Cluster in the W-cloud.[3]
The active galactic nucleus (AGN) contains a 400 million solar mass supermassive black hole (SMBH)[4] with an 800 light-year-wide spiral-shaped disk of dust fueling it.[5]
The galaxy is estimated to be about 60 thousand light-years across,[6] and the jet is estimated to span about 88 thousand light-years.[7]
