V821 Arae (also referred as GX 339-4 and GRS 1009-45) is a moderately strong variable galactic low-mass X-ray binary source that contains a black-hole and G-class white-yellow star. System was firstly observed in 21st century and helped astronomers of those times in understanding black holes variable accretion disks. The system is a regular X-ray emitter because of the stellar matter, that flows from the star to the black hole and forms a disk around the latter. A strong variable relativistic jet is also usually observed. System holds only one ice world planet that regularly witnesses dances of the black hole and the star.
