Kepler-10b is one of several exoplanets discovered by NASA's Kepler Mission, and as of January 2011 the smallest transiting exoplanet known. It is the first rocky planet to be discovered by the Kepler mission. The discovery of this exoplanet is based on eight months of data collected from May 2009 to early January 2010.[2] Kepler-10b is 1.4 times the size of the Earth.
Significance[editar]
The discovery of Kepler-10b is particularly significant since it increased the probability of finding more rocky planets and thus finding planets similar to our own.
Star[editar]
The exoplanet’s star, Kepler-10, was the first one identified as capable of harboring a small transiting planet, placing the star at the top of the list for ground-based observations using the W.M. Keck Observatory 10-meter telescope in Hawaii. Kepler-10 is located 560 light-years from our solar system and is approximately the same size as our sun. The star is estimated to be 11.9 billion years old.
