Based on recent discoveries, the exoplanet Gliese 12 b is the closest known Earth-sized planet, described as temperate and transiting, making it a significant find in the search for Earth-like worlds.
Understanding Gliese 12 b
Gliese 12 b, or Gl 12 b, is a fascinating exoplanet located approximately 40 light-years away. This discovery is highlighted in two research papers: Kuzuhara et al. 2024 and Dholakia et al. 2024. NASA has also released information and visualizations on the system.
Here's a breakdown of what makes Gliese 12 b so interesting:
- Size and Temperature: Gliese 12 b is roughly the same size as Earth and is considered temperate, which means it could potentially support liquid water on its surface.
- Transiting: It transits its star, which allows scientists to study its atmosphere using advanced telescopes.
- Proximity: Being 40 light-years away makes it one of the closest transiting exoplanets.
This combination of features makes it a prime candidate for further research. It represents a significant step forward in the search for potentially habitable worlds beyond our solar system.
