GJ 1252 is a red dwarf star located 66.5 light-years (20.4 parsecs) away from the Solar System in the constellation of Telescopium. The star has about 38% the mass and 39% the radius of the Sun, and a temperature of about 3,458 K (3,185 °C; 5,765 °F). GJ 1252 is orbited by one known exoplanet.
Planetary system
GJ 1252 was found to have a planet, GJ 1252 b, in 2019 using transit observations from TESS. It is a terrestrial planet larger than Earth, with about 1.3 times the mass and 1.18 times the radius of Earth. Orbiting its star with a very short period of just 12.4 hours, it is presumably tidally locked. Secondary eclipse observations have shown that GJ 1252 b lacks a significant atmosphere, similar to LHS 3844 b and TRAPPIST-1b, and have measured its dayside temperature at about 1,410 K (1,140 °C; 2,080 °F).
