For first time, agency's Transiting Exoplanet Survey Satellite has discovered roughly Earth-size planet in Habitable zone of its host star, zone of orbital distances where liquid water could be stable on world's surface, researchers announce today. Newfound Exoplanet, Known As TOI 700 D, Lies Just 101. 5 light-years from Earth, making it good candidate for follow-up observations by other instruments, scientists add. TESS was designed and launched specifically to find Earth-size planets orbiting nearby stars, Paul Hertz, Astrophysics division director at NASA Headquarters in Washington, said in statement. Planets around nearby are easiest to follow up with larger telescopes in Space and on Earth. Discovering TOI 700 D is key science finding for TESS. TESS, which launched in April 2018, hunts for planets using transit method, looking for telltale dips in stellar brightness caused by orbiting worlds crossing stars' face from Satellite's perspective. This same strategy was used to great effect by NASA's Kepler Space Telescope, which discovered about percentage of roughly 4 000 known Exoplanets. TESS found three planets circling star TOI 700. One of other planets is red dwarf, about 40 percentage as massive, 40 percentage as wide and 50 percentage as hot as Earth's Sun. Innermost world, TOI 700 B, is roughly Earth-size and completes one every 10 Earth days. Center Planet, TOI 700 is 2. 6 times bigger than our planet, meaning it's likely gassy mini-Neptune, and zips TOI 700 every 16 days. TOI 700 D, outermost known planet in system, is really intriguing one. It's just 20 percentage larger than Earth and completes one every 37 days. Alien World Receives 86 Percentage Of Stellar Energy That Earth Gets From Sun, Putting TOI 700 D In Habitable Zone, Discovery Team Members Say. All three planets may be tidally locked to TOI 700, always showing it same face just as Earth's Moon only ever shows us Its near side. But tidal locking doesn't necessarily preclude possibility of life on alien world, astronomers say. And there's more good along these lines regarding TOI 700. In 11 months of data, we saw no flares from star, which improves chances TOI 700 D is habitable and makes it easier to model atmospheric and surface conditions, discovery team leader Emily Gilbert, graduate student at University of Chicago, say in same statement. TESS isn't only spacecraft that has spotcheck evidence of TOI 700 D. Different teams of researchers use NASA's Spitzer Space Telescope to confirm existence of alien Planet. Give impact of this discovery that it is TESSs first Habitable-zone Earth-size Planet, we really want our understanding of this system to be as concrete as possible, team leader Joseph Rodriguez, astronomer at Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, said in same statement. Spitzer saw TOI 700 transit exactly when we expected it to, Rodriguez add.
