Paul Lissaur: The planet we've announced today is probably the most Earth-like world to have been discovered since the dawn of history.
Narrator: I'm Bob Karson with "The Discovery Files" -- new advances in science and engineering from the National Science Foundation.
That was Paul Lissaur, part of a team of astronomers supported by NSF and NASA on a major historical first -- a rocky planet orbiting a star similar to our sun.
Though a little large to be earth's body double -- at least twice the size and 7 to 8 times its mass -- the planet could possibly support an atmosphere.
If you're planning a vacation on this remote body, pack some extra sunscreen. Surface temperatures are estimated to be 400 to 700 degrees.
Its orbit is extremely fast as well...47 hours. So if you lived there, taxes would be due about every 2 days.
Even with its differences, of the other 154 extra-solar planets discovered, none has exhibited such striking similarities to earth.
