washington, Scientists have got a big success regarding the long-running search for a planet like Earth. According to a CNN News report, a mission by the US space agency NASA has spotted an Earth-sized exoplanet orbiting a small star about 100 light-years away. NASA scientists believe that this planet named TOI 700e is probably rocky and is 95% the size of our world. This celestial body is the fourth planet observed orbiting the small, cool M dwarf star TOI 700. All the exoplanets were found by NASA’s Transiting Exoplanet Survey Satellite, or TESS mission.
Let us tell you that even in the year 2020, a planet named TOI 700 d was discovered which is the size of the Earth. Both these exoplanets exist at such a distance from their star that liquid water can potentially exist on their surfaces. The potential for liquid water suggests that the planets themselves may be habitable for life. The discovery of a fourth planet was announced Tuesday 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 closest to the TOI 700 star is TOI 700 b, which is 90% the size of Earth and completes its orbit around the star every 10 Earth days. Then there is TOI 700 c, which is 2.5 times bigger than our planet and completes one orbit of the star every 16 days. These two planets are likely tidally locked, meaning they always show the same side to the star – just as the same side of the Moon always faces Earth. The star’s habitable zone contains two exoplanets, D and E, which complete their orbits in 37 days and 28 days, as they are slightly more distant from the star. The newly announced planet E is actually located between planets C and D.
