PKS 1302−102 is a quasar in the Virgo constellation, located at a distance of approximately 1.1 Gpc (around 3.5 billion light-years).[1] It has an apparent magnitude of about 14.9 mag in the V band with a redshift of 0.2784.[1] The quasar is hosted by a bright elliptical galaxy,[3] with two neighboring companions at distances of 3 kpc and 6 kpc. The light curve of PKS 1302−102 appears to be sinusoidal with an amplitude of 0.14 mag and a period of 1,884 ± 88 days, which suggests evidence of a supermassive black hole binary.[4]
