GJ 1002
# GJ 1002

GJ 1002 (or Gliese 1002) is a nearby red dwarf star, located 15.8 light-years (4.8 parsecs) away from the Solar System in the constellation of Cetus. The star has 12% the mass and 14% the radius of the Sun, and a temperature of 3,024 K (2,751 °C; 4,984 °F). It hosts a system of two known exoplanets.

## Planetary system

Two planetary companions to GJ 1002 were discovered in 2022 via radial velocity. Both have minimum masses close to that of Earth and orbit within the habitable zone of their star. While these planets do not transit their host star, it may be possible to determine the presence and composition of atmospheres with future instruments such as the ANDES spectrograph for the Extremely Large Telescope.
