The NASA researchers at Goddard Space Flight Center in Greenbelt, Maryland, made 20 possible environments of the planet to gauge whether any version would offer surface pressures and temperatures suitable for habitability. Their climate models examined several atmospheric compositions and surface types generally associated with what the scientists call as potentially habitable worlds. It is anticipated that the wind patterns and cloud formations of TOI 700 d to be extremely different from Earth’s because it is tidally locked to the star.
One simulation included TOI 700 d to be covered in the ocean with a carbon-dioxide-dominated atmosphere, which is similar to what the scientists suspect covered Mars in its young days. This model contains a deep cloud layer on its star-facing side. On the other hand, another model depicts the planet as an all-land, cloudless version of the modern Earth, where the winds blow away from TOI 700d’s night side and converge on the point that directly faces the star.
