📖 Introduction
Discovery of Gliese 12 b
In May 2024, NASA announced a significant discovery in the field of exoplanet research. This announcement pertained to an Earth-sized celestial body.
The newly identified exoplanet has been officially named Gliese 12 b. It is particularly noteworthy for being categorized as potentially habitable.
Proximity to Earth and Location
Gliese 12 b is situated approximately 40 light-years away from our home planet, Earth.
This relatively close distance makes it one of the closest known potentially habitable planets discovered outside our solar system to date.
A light-year is a unit of astronomical distance equivalent to the distance that light travels in one year, which is about 9.46 trillion kilometers.
Surface Temperature and Habitability Potential
The average surface temperature of Gliese 12 b has been measured at +42 °C (107 °F).
This temperature is considerably lower than that of the vast majority of the over 5,000 exoplanets discovered so far, making it a prime candidate for further study.
A moderate surface temperature is a critical factor for the potential existence of liquid water, which is considered essential for life as we know it.
Understanding 'Potentially Habitable'
The designation 'potentially habitable' indicates that a planet possesses conditions that *could* support life, rather than confirming its presence.
- It typically implies the planet is located within its star's habitable zone (Goldilocks Zone).
- It suggests the possibility of conditions conducive to liquid water on its surface.
- Further atmospheric analysis is required to confirm true habitability.
UPSC often tests knowledge on recent space discoveries and the scientific criteria for exoplanet habitability. Understand the significance of temperature and distance.
