Gliese 229 is a nearby triple star system of a red dwarf star and two brown dwarfs about 18.79 light-years away in the constellation Lepus. In 2014 and 2020, radial velocity signals reported the detection of two mini-neptunes orbiting the primary star (A). However, follow-up studies in 2025 failed to verify their existence, with the signals most likely generated by stellar activity instead
