The new planet discovered by NASA could be a “water world”
is a giant exoplanet, located 100 light years from Earth, which would harbor a very deep ocean on its surface.
Charles Cadier of the University of Montreal and his research team describe the discovery in The Astrophysical Journal .
“TOI-1452 b is one of the best ocean planet candidates we have found so far,” Cadier said.
TOI-1452 b , is located 100 light-years away in the Dragon (or Dragon) constellation, orbits, one of two small stars in a binary system.
While the planet orbits its star in just 11 days, the world is in the system’s so-called habitable zone.
This is about two and a half times the distance between the Sun and Pluto.
The stars, identified as red dwarfs, are so close together that NASA ‘s TESS space telescope initially detected them as a single object whose light dims every 11 days as it passes by exoplanets.Based on this signal, astronomers suspect that it is an object 70% larger than Earth.
This confirms to scientists that it is indeed an exoplanet, possibly with a lot of water. The Japanese team was also able to confirm this observation.
Cadier and his collaborators suspect that the planet may be completely covered in water, similar to some of the moons of Saturn or Jupiter, but its water is frozen, at least on the surface.
