NASA’s Kepler Mission Discovers Its First Rocky Planet: Kepler-10b
In January, NASA announced that Kepler has found its first rocky planet which they named “Kepler-10b”. This is really exciting news because this is the first time we have discovered a rocky planet orbiting a sun other than ours. Other planets that have been discovered have been gas planets, like Jupiter. Kepler-10b cannot support life because it is too close to its sun (called Kepler 10). In fact, Kepler-10b is 20 times closer to its sun that Mercury is to our sun. Thus, Kepler-10b is not in the “habitable zone” meaning that It is too hot for water and therefore it is unlikely that life can be found on this planet. Kepler-10b has a very fast year - it orbits its sun in .84 days! Click this link to see a video on NASA about the discovery: Kepler-10b Discovery.
