Astronomers Have Discovered Two Potentially Liveable Exoplanets
The celestial bodies are located about 12.5 light-years from Earth at the Teegarden star, which is classified as a red dwarf, and both are close in size to the globe. The finds were called Teegarden b and Teegarden c.
The planets are relatively close to their star, revolving around it in just 4.9 and 11.4 days. However, they do not rotate around their axis, and one of their sides is always facing the star. This means that there is no day / night cycle.
Researchers admit that it is not known what kind of atmosphere the planets have, and only assume that the surface temperature of Teegarden b with a 60 percent probability ranges from 0 to plus 50 degrees Celsius, while on Teegarden c it should be much colder than on Mars with its temperature spread from −153 to +35.
Nevertheless, as scientists hope, water and conditions suitable for life may be present on both planets.
It is noted that scientists discovered the star and the nearby planets back in 2003, but only now were able to focus on their study.
