!Discovering a planet that may be habitable for life, you can live on it for 3158 years
Scientists have discovered a planet 100 light-years away from Earth that is not likely to be habitable but would have a life expectancy of 3,158 years.
Two planets orbiting the star TOI-4306 have been discovered by an international team of scientists led by astrophysicist Laetitia Delrez . The temperature of this star is half the temperature of the Sun and its size is 6.5 times smaller than it.
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. The inner planet is too hot to hold liquid water but the outer planet is able to do so making it the habitable planet of the two.
This second planet receives the same amount of stellar radiation that our Earth receives from the Sun, and thus could have liquid water on its surface.
Dr. Robert Wells of the University of Bern and the National Cancer Research Council.
The first planet, called LP 890-9b or TOI-4306b, is about 30 percent larger than Earth and orbits its star in just 2.7 days. And because the current average life expectancy of a person on Earth is about 73.5 years. This means that the life expectancy on TOI-4306b, which has a much shorter year due to its extremely short orbit, will be 9,943 years.
The seasons on this planet will pass in the blink of an eye, one minute it snows, the next it rains and then summer.
This planet was initially identified by NASA's Transiting Exoplanet Survey Satellite (TESS). TESS is out on a space mission dedicated to searching for exoplanets in nearby orbiting stars.
Researchers at the University of Liège used their SPECULOOS ground-based telescopes to confirm and characterize this planet, as well as to find any other planets TESS might have missed.
SPECULOOS telescopes are also equipped with highly sensitive infrared cameras, so it has become very easy for them to observe these types of stars with high precision. This is why they were also able to spot the other planet called LP 890-9c, or SPECULOOS-2c.
This planet is about 40 percent larger than Earth and orbits in about 8.5 days. So if you lived on this planet, you could live 3158 years.
This means that these planets are ideal candidates for scientists to study and determine if there are any possible traces of life in their atmospheres. LP 890-9c is currently the second most favored target for study by the James Webb Telescope, but so far nothing is confirmed about its habitability.
