The exoplanet exists in their star's habitable zone, or just the right distance from the star that liquid water might potentially exist on their surfaces.
The discovery of the fourth planet was announced at the 241st meeting of the American Astronomical Society in Seattle, and a study about the exoplanet has been accepted for publication by The Astrophysical Journal Letters.The planet, named TOI 700 e, is likely rocky and 95% the size of our world. The celestial body is the fourth planet to be detected orbiting the small, cool M dwarf star TOI 700.
"This is one of only a few systems with multiple, small, habitable-zone planets that we know of," said lead study author Emily Gilbert, a postdoctoral fellow at NASA's Jet Propulsion Laboratory in Pasadena, California, in a statement. Closest to the star is TOI 700 b, which is 90% of Earth's size and completes one rapid orbit around the star every 10 Earth days. Then there's TOI 700 c, which is 2.5 times bigger than our planet and finishes one orbit around the star every 16 days. These planets are both likely tidally locked, meaning they always show the same side to the star - much like how the same side of the moon always faces Earth.
