Gliese 1132 (often shortened to GJ 1132) is a small red dwarf star about 41 light-years (12.6 parsecs) away from Earth[1] in the constellation Vela. In 2015, it was revealed to have a hot rocky Earth-sized planet orbiting it every 1.6 days, which was later determined to have an atmosphere. In 2018, two more potential planets were revealed.[3]
