Scientists confirmed the find, called TOI 700 d, using NASA's Spitzer Space Telescope and have modeled the planet's potential environments to help inform future observations. \n\nTOI 700 is a small, cool M dwarf star located just over 100 light-years away in the southern constellation Dorado. It's roughly 40 of the Sun's mass and size and about half its surface temperature. The star appears in 11 of the 13 sectors TESS observed during the mission's first year, and scientists caught multiple transits by its three planets. \n\nThe innermost planet, called TOI 700 b, is almost exactly Earth-size, is probably rocky and completes an orbit every 10 days. The middle planet, TOI 700 c, is 2.6 times larger than Earth -- between the sizes of Earth and Neptune -- orbits every 16 days and is likely a gas-dominated world. TOI 700 d, the outermost known planet in the system and the only one in the habitable zone, measures 20 larger than Earth, orbits every 37 days and receives from its star 86% of the energy that the Sun provides to Earth. All of the planets are thought to be tidally locked to their star, which means they rotate once per orbit so that one side is constantly bathed in daylight. \n\nThe Spitzer data increased scientists' confidence that TOI 700 d is a real planet and sharpened their measurements of its orbital period by 56% and its size by 38%. It also ruled out other possible astrophysical causes of the transit signal, such as the presence of a smaller, dimmer companion star in the system. \n\nWhile the exact conditions on TOI 700 d are unknown, scientists used current information, like the planet's size and the type of star it orbits, and modeled 20 potential environments for TOI 700 d to gauge if any version would result in surface temperatures and pressures suitable for habitability. \n\nOne simulation included an ocean-covered TOI 700 d with a dense, carbon-dioxide-dominated atmosphere similar to what scientists suspect surrounded Mars when it was young. The model atmosphere contains a deep layer of clouds on the star-facing side. Another model depicts TOI 700 d as a cloudless, all-land version of modern Earth, where winds flow away from the night side of the planet and converge on the point directly facing the star. \n\nMusic credit: \"Family Tree\" from Universal Production Music\n\nRead more: https:\/\/www.nasa.gov\/feature\/goddard\/2020\/nasa-planet-hunter-finds-its-1st-earth-size-habitable-zone-world\n\nCredit: NASA's Goddard Space Flight Center\nScott Wiessinger (USRA): Lead Producer\nChris Smith (USRA): Lead Animator\nJeanette Kazmierczak (University of Maryland College Park): Lead Science Writer\nGabrielle Engelmann-Suissa (USRA): Scientist\nBarb Mattson (University of Maryland College Park): Narrator\nGeronimo Villanueva (Catholic University of America): Visualizer\n\nThis video is public domain and along with other supporting visualizations can be downloaded from the Scientific Visualization Studio at: http:\/\/svs.gsfc.nasa.gov\/13496\n\nIf you liked this video, subscribe to the NASA Goddard YouTube channel: http:\/\/www.youtube.com\/NASAExplorer\n\nFollow NASA\u2019s Goddard Space Flight Center\n\u00b7  Instagram http:\/\/www.instagram.com\/nasagoddard\n\u00b7  Twitter http:\/\/twitter.com\/NASAGoddard\n\u00b7  Twitter http:\/\/twitter.com\/NASAGoddardPix\n\u00b7  Facebook: http:\/\/www.facebook.com\/NASA.GSFC\n\u00b7  Flickr http:\/\/www.flickr.com\/photos\/gsfc","thumbnailUrl":["https:\/\/i.ytimg.com\/vi\/QU0qsIGS6MQ\/default.jpg","https:\/\/i.ytimg.com\/vi\/QU0qsIGS6MQ\/mqdefault.jpg","https:\/\/i.ytimg.com\/vi\/QU0qsIGS6MQ\/hqdefault.jpg","https:\/\/i.ytimg.com\/vi\/QU0qsIGS6MQ\/sddefault.jpg","https:\/\/i.ytimg.com\/vi\/QU0qsIGS6MQ\/maxresdefault.jpg"],"uploadDate":"2020-01-07T00:15:01+00:00","duration":"PT3M17S","embedUrl":"https:\/\/www.youtube.com\/embed\/QU0qsIGS6MQ","publisher":{"@type":"Organization","@id":"https:\/\/www.youtube.com\/channel\/UCAY-SMFNfynqz1bdoaV8BeQ#Organization","url":"https:\/\/www.youtube.com\/channel\/UCAY-SMFNfynqz1bdoaV8BeQ","name":"NASA Goddard","description":"Your friendly neighborhood space flight center. \ud83d\udc69\u200d\ud83d\udd2c\ud83d\ude80\n\nNASA's Goddard Space Flight Center is home to the nation's largest organization of combined scientists, engineers and technologists that build spacecraft, instruments and new technology to study Earth, the Sun, our solar system and the universe.\n\nNamed for American rocketry pioneer Dr. Robert H.
