A team of UK scientists has identified a new planet, named Gliese 12b, which is believed to have the capability of sustaining human life. The discovery, made using NASA’s TESS satellite, places the planet at a relatively short distance from Earth, cosmically speaking.
With an average surface temperature of around 42 degrees Celsius, conditions on Gliese 12b may be conducive to the presence of liquid water—an essential criterion for habitability as defined by researchers. Notably, this exoplanet is one of the relatively rare celestial bodies outside our solar system that could be suitable for human life.
Larissa Palethorpe from the University of Edinburgh, amongst other international researchers, contributed to this significant find. “Although it might be challenging to dwell there due to the temperature, the existence of liquid water on its surface is theoretically possible,” observes Palethorpe.
The indicators of Gliese 12b’s size and orbit were comprehended within a year, with particular emphasis on its Earth-like dimensions and comfortable temperatures. Ms. Palethorpe notes the rarity of smaller planets like Gliese 12b, highlighting the importance of such discoveries to gauge the frequency of Earth-like planets across the galaxy.
Gliese 12b’s distance of 40 light years from us means that, as of now, reaching the planet with our fastest spacecraft would take an unimaginable 300,000 years. This exoplanet orbits a cool red dwarf known as Gliese 12, located in the constellation Pisces, and completes an orbit in just 12.8 days.
The pursuit to understand more continues, as scientists like Professor Thomas Wilson from the University of Warwick aim to study Gliese 12b’s atmosphere, which could hold further clues to the planet’s habitability.
Gliese 12b’s discovery opens up intriguing possibilities, such as the likelihood of an atmosphere that resembles Earth’s, though Palethorpe warns that an inhospitable atmosphere, or the complete absence of one, could significantly diminish the chances of habitability.

FAQ Section
What is Gliese 12b?
Gliese 12b is a new planet discovered by UK scientists that could potentially support human life due to its Earth-like size and relatively mild average temperature, making it one of the few known planets outside our solar system that might be habitable.
How far is Gliese 12b from Earth?
Gliese 12b is located approximately 40 light years away from Earth.
Can we travel to Gliese 12b?
As of now, it would take our fastest spacecraft about 300,000 years to reach Gliese 12b, making travel to the planet currently unfeasible.
Who discovered Gliese 12b and how?
A team of international scientists led by UK researchers, including Larissa Palethorpe from the University of Edinburgh, discovered Gliese 12b using NASA’s Transiting Exoplanet Survey Satellite (TESS).
What makes a planet habitable?
A habitable planet is one where conditions could allow for the presence of liquid water on its surface. This usually means a planet that has a suitable temperature range and, ideally, an atmosphere akin to Earth’s.
Conclusion
The discovery of Gliese 12b by UK scientists is a breakthrough in the search for Earth-like planets that could support human life. While the prospect of colonization is not viable with current technology, this exoplanet provides a tantalizing glimpse into the potential for habitability beyond our solar system. Ongoing research focusing on the planet’s atmosphere and composition will continue to shed light on its similarities to Earth and its potential for supporting life.
