Gliese 12 b: A Potentially Temperate Exoplanet Exo-Venus
Gliese 12 b was identified using NASA’s Transiting Exoplanet Survey Satellite (TESS) and the European Space Agency’s CHaracterizing ExOPlanets Satellite (CHEOPS). The planet completes a quick orbit around its star, Gliese 12, every 12.8 Earth days. However, there’s a twist: Gliese 12 is a red dwarf star, significantly cooler and smaller than our Sun. This cooler star system offers Gliese 12 b a chance at harboring liquid water, a crucial ingredient for life as we know it.
Red Dwarfs and the Hunt for Habitable Worlds
Red dwarf stars are abundant in our galaxy, and many exoplanets have been found orbiting them. The challenge is that these planets often reside in very close orbits, which would typically render them too hot for life. But Gliese 12 b seems to be in a sweet spot.
While Gliese 12 is only 27% the size of our Sun and has a surface temperature 40% cooler, Gliese 12 b receives 1.6 times the solar energy Earth does. Early calculations estimate an average surface temperature of 107 degrees Fahrenheit (42 degrees Celsius) for Gliese 12 b.
The Crucial Role of Atmosphere: Earth-Like or Exo-Venus -Like?
The key to Gliese 12 b’s potential habitability lies in its atmosphere. Without an atmosphere, the surface temperature would likely match the calculations. However, an Earth-like atmosphere could distribute heat effectively, creating conditions suitable for life.
On the other hand, a scenario like Venus is also possible. Venus, our solar system’s hottest planet, possesses a super-dense atmosphere of carbon dioxide, trapping heat and causing scorching temperatures that could melt lead.
Understanding the atmospheric composition of Gliese 12 b is critical. This knowledge could help scientists predict conditions on other exoplanets orbiting red dwarfs. Luckily, Gliese 12 b is close enough for the James Webb Space Telescope to potentially analyze its atmosphere.

By observing how starlight passes through the exoplanet’s atmosphere, Webb can identify the wavelengths of light being absorbed. This information can reveal the atmospheric composition, indicating whether Gliese 12 b possesses a thin atmosphere, a thick atmosphere like Venus, or something entirely different. http://ExtreneTech.com
A Placid Red Dwarf and the Search for Life
Another interesting aspect of Gliese 12 b is the calmness of its host star. Red dwarf stars spew out powerful solar flares that can rip apart the atmospheres of planets orbiting them.. However, Gliese 12 appears to be a more placid example, offering a potentially stable environment for an atmosphere to exist.
Gliese 12 b: A Stepping Stone in Exoplanet Research
The discovery of Gliese 12 b is a significant leap forward in our quest to understand exoplanets. This newfound world could be a stepping stone, allowing scientists to study the atmospheres of planets orbiting cool stars and assess their potential for harboring life.
The upcoming analysis using the James Webb Space Telescope will be crucial in this endeavor. If scientists can determine the atmospheric composition of Gliese 12 b, it will provide a wealth of information about the possible diversity of exoplanets orbiting red dwarf stars and open a new chapter in the search for life beyond our solar system.UFO : Man’s Seven-Minute Encounter with a Glowing Barbell
