From Texas Standard:
Big news this morning from NASA’s planet-hunting mission: The Kepler Space Telescope at the University of Texas' McDonald Observatory has revealed the most Earthlike planet found to date, researchers say. The planet, called Kepler-452b, lies in the constellation Cygnus, about 1,400 light years from Earth. It qualifies as super-Earth-sized, as it's about 1.6 times larger than Earth, and its orbital period is quite similar to ours, at 385 days.
The Kepler scope was launched in 2009 to detect Earth-size planets in or near the habitable zones of distant stars — planets that have the potential to sustain life like that on Earth.
“We are pushing toward Earth 2.0,” McDonald Observatory astronomer Michael Endl said in a press release. “This planet is probably the most similar to Earth yet found.”
