Description

HFG-1 was discovered in 1982 by Heckathorn, Fesen and Gull. Its central star is actually a binary star system, V664 Cas (magnitude 14) that is moving through our galaxy. V664 Cas consists of a white dwarf star and a large red giant, rotating around their centre of gravity every 14 hours. As HFG 1 moves through the ISM a bowshock is produced in front of it as well as a red trail of gas in its wake. Outer diameter about 15 arcmin.
