Kepler Mission Finds A Hot And Rocky Expolanet

January 11, 2011

Kepler Space Mission has found it’s first exoplanet, Kepler-10b. The announcement was made today in Seattle at the meeting of American Astronomical Society. It’s one of the smallest exoplanet discovered outside our solar system¬† and unlike other exoplanets found, this one is dense and rocky (or molten). It’s density is about 8.8 g/cc. The planet is 560 light years away, size is about 1.4 times that of earth and mass is about 4.6 times that of earth. It rotates very close to it’s sun, almost 20 times as close as Mercury is to our Sun, making it extremely hot and thereby makes it un-habitable (surface temperature¬†is more than 2,500 F on the side which faces sun). I will try to write in more detail as to how the measurements of such planets are done (size, density, orbit radius etc.), probably tomorrow, meanwhile the¬† video below will give you a good idea about this new discovery. Looks like it’s going to be an exciting year in discovery of more exoplanets and maybe few of them will be in habitable zones.
