Researchers say the new planet is too close to its sun to support known forms of life, with a surface temperature estimated at 1,200 degrees Celsius (2,192 Fahrenheit). But previous studies suggest that when one planet is discovered orbiting a sun, there are usually others in the same system. LONDON/CAPE CANAVERAL, Florida: Astronomers have found a new planet, the closest yet outside our solar system and just an astronomical stone's throw away at four light years, raising the chances of finding a habitable planet in Earth's neighborhood.
The new Earth-sized planet, announced in science journal Nature by Stephane Udry and Xavier Dumusque at the Geneva Observatory, orbits one of the suns in Alpha Centauri, roughly 25 trillion miles away.
