Gliese 12 b: Discovery of a Temperate Exoplanet Orbiting a Red Dwarf
Gliese 12 b: Discovery of a Temperate Exoplanet Orbiting a Red Dwarf0A newly discovered exoplanet, Gliese 12 b, has captured the interest of astronomers due to its temperate surface temperature and proximity to its red dwarf star. This planet, similar in size to Venus but slightly smaller than Earth, orbits its host star, Gliese 12, at 7 percent of the distance between Earth and the Sun. It has an estimated surface temperature of 42 degrees Celsius, among the lowest of the 5,638 discovered exoplanets, making it a promising candidate for a habitable planet.

Gliese 12 b, located 40 light-years away from our planet, offers a rare opportunity to study whether planets orbiting cool stars can retain their atmospheres and support liquid water, essential for life. Unlike many red dwarfs, Gliese 12 is relatively calm, lacking the powerful X-ray flares that can strip away planetary atmospheres, increasing the chances that Gliese 12 b could retain its own.

Gliese 12 b: Discovery of a Temperate Exoplanet Orbiting a Red Dwarf4With the James Webb Space Telescope, future studies will analyze Gliese 12 b’s atmosphere and its composition. As the planet frequently orbits its host star, astronomers may make detailed observations through transit spectroscopy, potentially uncovering the presence of various gases and habitability indicators.

Gliese 12 b’s discovery, made using NASA’s Transiting Exoplanet Survey Satellite (TESS) and European Space Agency’s CHEOPS (CHaracterising ExOPlanets Satellite), marks significant progress in the search for habitable worlds. As research advances, this exoplanet could provide crucial insights into the conditions necessary for life beyond our solar system.
