Gliese 12 b (or Gl 12 b) is a planet that was discovered in 2024.
This newly discovered exoplanet, Gliese 12 b, is located approximately 40 light-years away from Earth. It's an exciting discovery because it's a transiting, temperate, and Earth-sized world, making it one of the closest such planets found to date. Its discovery has been documented in research papers by Kuzuhara et al. (2024) and Dholakia et al. (2024). NASA has also released information and visualizations about this planetary system.
The discovery is significant due to the planet's size and temperature, which are comparable to Earth, suggesting the possibility of liquid water and potentially habitable conditions. Further research is needed to determine if the planet has an atmosphere and to assess its true habitability.
