NASA’s new exoplanet hunter Transiting Exoplanet Survey Satellite has discovered its first Earth dimension world. The planet, Hi-def 2174 9 c, is about 89 percent of Earth’s diameter, NASA said on Tuesday. The planet orbits Hi-def 2174 9, a K type star with about 70 percent of the Sun’s mass situated 53 light years away from the south-east constellation Reticulum, also is the second planet that TESS has recognized in the system. Launched on Apr 18, 2018, TESS is the next step in the search for planets outside our solar system, such as those that could support life.
It’s on a mission to survey 200, 000 of the brightest stars near the Sun to search for transiting exoplanets. The planet, Hi-def 2174 9 c, is the 10th confirmed planet discovered by TESS, and hundreds of additional candidates are being studied. The new world is rocky and circles quite close to his star completing one orbit in only under eight times. The planet is very sexy, with surface temperatures probably like large as 427 degrees Celsius, NASA said. Researchers at the MIT And the Carnegie Institution for Science analyzed TESS transit data from the first four sectors of TESS observations to discover 11 periodic dips in the star’s brightness. From this, they determined that the star’s light has been partially blocked by a planet about the size of Earth. The star that Hi-def 2174 9 c orbits are bright and comparatively nearby, and for that reason ideal for in-depth follow-up studies, NASA said.
