Scientists have discovered a new 'super-Earth' type planet that might be suitable for life, about 100 light-years away. The planet orbits its own sun in a matter of days.
while using Earth-based telescopes to confirm the existence of a different planet initially discovered by a NASA satellite in the same solar system.
NASA's satellite found planet LP 890-9b, which is about 30% larger than Earth and orbits its sun in just 2.7 days. ULiège researchers used their telescopes in Chile and Spain to take a closer look at the planet with high-precision cameras. That's when the stargazers discovered another planet, LP 890-9c , which is 40% larger than Earth and takes 8.5 days to orbit its sun.Francisco Pozuelos, a researcher at the Institute of Astrophysics of Andalusia and one of the main co-authors of the paper, said in a news release that the planet could be suitable to life despite being a mere 3.7 million miles from its sun. Earth, by comparison, is located over 93 million miles away from our sun.
"Although this planet orbits very close to its star, at a distance about 10 times shorter than that of Mercury around our Sun, the amount of stellar irradiation it receives is still low, and could allow the presence of liquid water on the planet's surface, provided it has a sufficient atmosphere," Pozuelos said."This is because the star LP 890-9 is about 6.5 times smaller than the Sun and has a surface temperature half that of our star.
