CHXR 73 is a star with 0.35 times the mass of the Sun, and NaN times its radius. It is located 620.92 light years away from the solar system and is estimated to be 0.002 billion years old, as compared to the Sun which is roughly 4.6 billion years old.
CHXR 73 is known to have 1 exoplanets in orbit around it.
CHXR 73 b was discovered by the Hubble Space Telescope observatory, in 2006-10, using the imaging method. Its semi-major axis is 210.00 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of CHXR 73 b is 3996.942 times the mass of Earth. The radius of CHXR 73 b is 12.300 that of Earth. At more than 50 Earth masses, CHXR 73 b is a gas giant, a planet whose mass is mostly made up of hydrogen and helium, like Jupiter and Saturn in our solar system.
