Scientists discover a habitable planet where people can live up to 3,158 years

Scientists have discovered a new planet that may not only be habitable, but also allow you to live up to 3,158 years. The discovery was made by a team of scientists led by Laetitia Delrez, an astrophysicist at the University of Liege, Belgium.

The average life expectancy on Earth is 73.5 years, and since LP 890-9c takes only 8.5 days to orbit its star, the years go by much faster, unlike the 365-day orbit of the our Earth around the sun. In theory, therefore, we could live up to 3,158 years on this planet.

100 light years away

With the help of NASA’s TESS space telescope, the researchers found the planet using the transit method. The telescope monitors the brightness of a star, looking for any attenuation that could be caused by planets passing in front of the star.

The ULiège researchers used their SPECULOOS telescopes on the ground to confirm and characterize this planet, and also probe the system deeply for other planets that may have been “lost” by TESS.

A habitable planet?

Located 100 light-years from Earth, scientists have discovered that the star, LP 890-9 or TOI-4306, is half as hot as our sun and 6.5 times smaller. Two planets orbit the star, one of them at the right distance from each other to hold liquid water on the surface.

The inner planet called LP 890-9b orbits the star in 2.7 days, while the outer planet called LP 890-9c takes about 8.5 days to do the same. The inner planet is too hot to hold liquid water, but the outer planet is capable of it, making it a habitable planet.

Super-Terre

Located in the constellation of Eridanus, the two planets orbiting the sun LP 890-9 are called “super-Earths” because they have a similar rocky composition and are approximately 30-40% larger than our Earth.

Wells points out that scientists will need to conduct more research to confirm whether humans can actually move on the LP 890-9c.

More research is needed

“This second planet receives roughly the same amount of stellar radiation that our Earth receives from the Sun and could therefore contain liquid water on the surface,” said study co-author Dr Robert Wells of the University of Bern.

“But it’s important not to jump to conclusions. Being in the right place does not guarantee a palm beach. For example, our neighboring planet Venus, a pressure cooker rich in CO2 at almost 500 ° C, is also close to this so-called habitable zone around the Sun. “

“To determine whether this planet can actually contain surface liquid water or not, we need to know more. This requires detailed observations, for example with the James Webb Space Telescope. “
