New planet discovered on which life is possible?
NASA has announced that TESS has found a world the size of Earth to live in, and the prerequisite for living is the presence of running water
Planet Hunter US Space Agency NASA’s TESS satellite has discovered the first, most likely habitable, planet the size of Earth. On the TOI 700, the temperature is half that of the Sun, and is about a hundred light-years away from Earth. The US Space Agency has announced that TESS has found a world the size of Earth to live in, and the prerequisite for living is the presence of running water, AFP reports.The discovery was presented at the 235th meeting of the American Association of Astronomers in Honolulu.
The discovered planet, the TOI 700 d, is one of three orbiting a sun-like star in the TOI 700 system, reports Hina.
The TOI 700d is farthest from its sun and it takes 37 days to make a circle around it. He is believed to always be on one side. The other two planets TOI 700 b and TOI 700 c are quite different.
The planet closest to that sun, the TOI 700 b, is also the size of the earth, but is a “rocky wasteland.” It takes 10 days to cycle around his own sun. The planet TOI 700 c is gaseous, the size of which is between Earth and Neptune. It takes 16 days to circle the sun. “TESS was created and launched with the targeted mission of finding a planet the size of the Earth orbiting nearby stars,” said Paul Herz of NASA’s astrophysical division.
AFP reports that TESS initially misclassified the star, meaning that the planets look bigger and hotter than they really are.
However, several amateur astronomers, including high school student Alton Spencer, who works with TESS members, pointed to the mistake.
“As we corrected the star’s parameters, the sizes of its planets decreased, so we realized that it was farthest from the size of Earth and was in the realm of possible life,” said Emily Gilbert of the University of Chicago. The discovery was later confirmed by the Spitzer Space Telescope.
