Liveable Conditions

The temperature on Gliese 12b is around 42°C, making it one of the few known planets where humans could theoretically survive. It meets the criteria for habitability, allowing for liquid water on its surface.

Scientific Collaboration

The discovery was made by a team of international scientists using NASA's Transiting Exoplanet Survey Satellite (TESS). The team calculated the planet's size, temperature, and movement within a year.

Challenges in Detection

Smaller planets like Gliese 12b are difficult to find. The detection of such a nearby Earth-sized planet is significant, allowing for further atmospheric analysis and a better understanding of potential Earth-like planets.

Planetary Characteristics

Gliese 12b's size is estimated to be comparable to Earth or slightly smaller, similar to Venus. It orbits its star, Gliese 12, every 12.8 days. Gliese 12 is a cool red dwarf located in the constellation Pisces.

Distance and Travel Time

Although Gliese 12b is only 40 light years away, current technology would require approximately 300,000 years to reach it using our fastest spacecraft.

Observation History

The light observed from Gliese 12b is from 40 years ago, highlighting the vast distances involved. Planets like Gliese 12b are rare, and this proximity allows for detailed examination.

Next Steps in Research

The next phase involves studying Gliese 12b's atmosphere to determine its habitability. Scientists aim to understand whether it has a thin, thick, or non-existent atmosphere, as this greatly affects its potential to support life.

Potential for Habitability

While Gliese 12b could have conditions suitable for life, further research is needed. The presence and nature of its atmosphere will be crucial in determining its habitability.
