CHXR 73 is a star in the constellation Chamaeleon, about 620 light-years away from Earth.
The star is located within Cha I, a molecular cloud. It has a low temperature of 3,490 K typical of red dwarfs, but unlike typical red dwarfs it has an unusually large radius of 0.83 R☉—this is because of its young age, only 8 million years.
