Nicknamed “ TOI-700e“, this exoplanet is located 102 light years from the solar system in the constellation of Dorade in the southern hemisphere.
It represents just over 95% of the diameter of the Earth. “She is interesting because she hasand an atmosphere and that’it is in the habitable zone; characteristics that resemble those of planet Earth”, according to the director of the Plane Tarium Rio Tinto Alcan in Montreal, Olivier Hernandez.
The closest planet to the star, TOI-700b, is almost exactly the size of Earth. Probably rocky, it goes through an orbit every ten days.
TOI-700c, meanwhile, is a gas giant about 2.6 times the size of Earth and orbits its star once every sixteen days, according to the same source.
The outermost planet in the system, TOI-700d, is 1.1 times larger than Earth and has an orbital period of 38 days. It is also in the habitable zone of its star.
These planets would be in synchronous rotation of their star, that is to say that they always present the same face to their star, according to the same source. “It’s about theone of the few systems with several small planets in the habitable zone that we know“said astronomer Emily Gilbert of NASA’s Jet Propulsion Laboratory in a statement.
