Two teams of scientists have discovered a theoretically habitable planet, smaller than Earth but bigger than Venus, orbiting a small star about 40 light-years away. The exoplanet, named Gliese 12b, orbits a cool red dwarf star situated in the constellation Pisces and is about 27% the size of our sun and 60% of its temperature, according to the two studies published on Thursday in The Astrophysical Journal Letters and Monthly Notices of the Royal Astronomical Society.
Understanding Gliese 12b To spot Gliese 12b, scientists used the publicly available data collected by NASA’s Transiting Exoplanet Survey Satellite — a telescope that stares at tens of thousands of stars every month, tracking their changes in brightness, which can be evidence of orbiting exoplanets. It is easier for astronomers to find exoplanets orbiting red dwarf stars since their relatively small size results in a greater dimming effect during each transit.
