GJ 1002 b (also designated as Gliese 1002 b) is a
habitable zone of its parent star.[3] GJ 1002 b has a minimum mass of 1.08 Earth masses and is estimated by the Planetary Habitability Laboratory to have 1.03 times the radius of Earth and a surface temperature of 261 Kelvin.[4]
Detection
GJ 1002 b was detected in 2022 via the radial velocity method and the planets mass was also detected via the radial velocity method.
Host star
The host star, GJ 1002, is a quiet M5.5V type red dwarf not believed to release flares that could harm the atmosphere.[5] The planet orbits its host star at a distance of 0.0457 AU (Astronomical units), with a 10.3 day orbital period and a 0.0 eccentricity.[6][7]
