GJ 1132 is a small red dwarf star 41.1 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. [6] In 2018, a second planet and a potential third were revealed. [4]

Mar 28, 2025 · GJ 1132 b is a super Earth exoplanet that orbits a M-type star. Its mass is 1.83704819 Earths, it takes 1.6 days to complete one orbit of its star, and is 0.0157 AU from its star. Its discovery was announced in 2015.

GJ 1132 b (also known as Gliese 1132 b) is an exoplanet orbiting GJ 1132, a red dwarf star 41 light-years (13 parsecs) from Earth, [1] in the constellation Vela. The planet is considered uninhabitable but was thought to be cool enough to possess an atmosphere. [2] GJ 1132 b was discovered by the MEarth-South array in Chile. [8]

Mar 11, 2021 · The rocky exoplanet GJ 1132 b, similar in size and density to Earth, possesses a hazy atmosphere made up of volcanic gases. Scientists say GJ 1132 b, orbiting a red-dwarf star about 41 light-years away, has some features in common with worlds in our own solar system as well as vast differences.

Mar 11, 2021 · This plot shows the spectrum of the atmosphere of an Earth-sized, rocky exoplanet, GJ 1132 b. The orange line represents the model spectrum. In comparison, the observed spectrum is shown as blue dots representing averaged …

Mar 25, 2021 · Scientists said on March 11, 2021, that – for the first time – they’ve detected a secondary atmosphere on an exoplanet orbiting a distant star. They used the Hubble Space Telescope to examine the...

Nov 16, 2015 · GJ 1132b is three times closer to us than any other Earth-sized planet we know of, and it orbits a small red dwarf star that is just one-fifth the size of the Sun. So that's one of the reasons why this discovery is unique.

Mar 12, 2021 · GJ 1132 b, once hailed as one of the most important planets outside the Solar System, appears to have lost its atmosphere - and has since grown a new one. This could be the first time we've identified an exoplanet that has significantly reformed …

The Featureless HST/WFC3 Transmission Spectrum of the Rocky Exoplanet GJ 1132b: No Evidence For A Cloud-Free Primordial Atmosphere and Constraints on Starspot Contamination

Nov 12, 2015 · The newfound world, named GJ 1132b, orbits a red dwarf star known as GJ 1132 (Gliese 1132), which is only 1/5 the size of the Sun. The star is also cooler and much fainter than our Sun, emitting just 1/200th as much light.
