Gliese 12 b (Gl 12 b) is described as the nearest, transiting, temperate, Earth-sized world found as of May 2024. Located approximately 40 light-years away, this exoplanet has garnered significant attention due to its characteristics and proximity.
Details about Gliese 12 b
Gliese 12 b is notable for several reasons:
- Size: It is considered Earth-sized, making it a potentially interesting candidate for further study.
- Temperature: It's described as temperate, suggesting it receives a level of stellar radiation that could allow for liquid water on its surface, although this is dependent on atmospheric conditions.
- Proximity: At 40 light-years away, it's one of the closest transiting Earth-sized exoplanets discovered to date. This relative nearness makes it a prime target for follow-up observations.
- Transit: Gliese 12 b transits its host star, Gliese 12. Transits are crucial because they allow scientists to determine the planet's size and, under certain conditions, analyze its atmosphere.
