Newly Discovered Earth-Size Planet Could Be Suitable for Life Nearby

May 24, 2024 | by The Jeuns

A new study has revealed the discovery of a potentially habitable exoplanet similar in size to Earth, located just 40 light-years away from our planet. Known as Gliese 12 b, this Venus-sized planet orbits a star that is 27% of the size of our sun, taking 12.8 days to complete its orbit.

Although it is uncertain whether Gliese 12 b has an atmosphere, researchers estimate its surface temperature to be around 107 degrees Fahrenheit (42 degrees Celsius). This temperature, while hot, is lower than many other exoplanets discovered so far, making it a potential candidate for hosting liquid water on its surface.

Researchers are eager to study Gliese 12 b further, using NASA’s James Webb Space Telescope to analyze its atmosphere and potentially uncover similarities or differences with Earth or Venus. Understanding the atmospheric conditions of exoplanets like Gliese 12 b can provide valuable insights into the factors that contribute to habitability in other solar systems.

The discovery of Gliese 12 b was made possible using data from NASA’s Transiting Exoplanet Survey Satellite, which monitors changes in the brightness of stars to detect potential orbiting planets. This finding highlights the ongoing efforts to explore and understand the vast expanse of our universe.

By studying planets like Gliese 12 b, scientists hope to gain a better understanding of the conditions necessary for life to exist beyond our own solar system. This research not only expands our knowledge of exoplanets but also offers valuable insights into the evolution of planetary systems.
