The planet, named “TOI 700 d,” is relatively close to Earth — 100 light years away, NASA’s Jet Propulsion Laboratory announced at the annual American Astronomical Society meeting in Honolulu, Hawaii. “TESS was designed and launched specifically to find Earth-sized planets orbiting nearby stars,” NASA astrophysics division director Paul Hertz said. Star TOI 700 is small, about 40 percent of our sun’s size and only about half as hot. It remains to be seen what TOI 700 d is made of. A third simulation predicted an all-land world, where winds flow from the planet’s dark side to its light one.
