GJ 1002 b (also designated as Gliese 1002 b) is a potentially habitable exoplanet located 16 light-years away, in the constellation of Cetus. [1] The planet, which has an Earth Similarity Index of 86%, is in the habitable zone of its parent star. [2] 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. [3]
GJ 1002 b was detected in 2022 via the radial velocity method, which was used to measure the planet's minimum mass. [1]
The host star, GJ 1002, is a quiet M5.5V type red dwarf not believed to release flares that could harm the atmosphere. [4] 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. [5] [6]
