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 —this is because of its young age, only 8 million years. Planetary system A companion, CHXR 73 b, has been found via direct imaging Any planet is an extremely faint light source compared to its parent star. For example, a star like the Sun is about a billion times as bright as the reflected light from any of the planets orbiting it. In addition to the intrinsic difficulty of .... CHXR 73 has a mass of about 12 Jupiters. This is close to the upper mass limit for planets, making its classification difficult.
