Just the other week, we reported that NASA’s planet-hunting mission called TESS managed to discover a viable potentially habitable exoplanet that’s the size of Earth.
This exoplanet is orbiting a star about 100 light-years from Earth, says the agency.
The info has been announced during the 235th meeting of the American Astronomical Society just the other day in Honolulu.
It was also reported by the latest data coming from CNN that this planet is a part of a multi-planet system around “TOI 700, a small, cool M-dwarf star in the Dorado constellation. It’s only about 40% of our sun’s mass and size, with half of the surface temperature.”
Does the exoplanet host life?
Now, Forbes analyzes the possibility that this planet could host life.
The online publication writes that if this planet has an atmosphere that’s similar to our planet, this means that it could have liquid water on its surface.
TESS is woking by surveying various slivers of the sky one month at a time in succession, according to the online publication.
It’s been also reported that the polar areas get the greatest coverage and these include the region where the star TOI 700 is also located.
TOI 700 has at least 3 plants that are orbiting it. It’s also worth noting that TOI 700 is an M-class red dwarf, and it has no flaring, “benefiting potential lifeforms,” Forbes says.
It’s been also revealed that the third planet from the star, which is called TOI 700d, is only 19% larger than Earth and receives 86% of the incident energy on Earth.
The planet could be tidally locked
Forbes also writes that the planet is probably tidally locked and it always faces its star. But, this doesn’t make it any less potentially habitable.
They also note that it all depends on the composition of the atmosphere and how energy flows there.
“A CO2-heavy atmosphere creates a uniformly hot world, where life is strongly disfavored. For contrast, a cloudless, oceanless world with an Earth-like atmosphere possesses sunward-directed winds and various temperature zones,” Forbes writes.
