The CoRoT-7b

 

CoRoT-7b

The planet CoRoT-7b is an exoplanet in the constellation of Monoceros at 489 light years from the earth. the planet CoRoT-7b is orbiting around the star CoRoT-7.it was first detected by CoRoT(Convection Rotation et Transits)space telescope on 3 February 2009 by using transit method.

the planet CoRoT-7b is smallest exoplanet ever detected. planet has 10009 km radius which is 1.58 times of the earth's radius.CoRoT-7b has 0.0283 mass that of the planet jupiter the planet mass is measure by HARPS(High And Radial Velocity Planet Searcher. spectrograph the planet CoRoT-7b is 23 times closer than the planet mercury to its host star. So that the planet CoRoT-7b has orbital period of 20 hours, meaning that if you are on the planet CoRoT-7b year is changed in 20 hours!CoRoT-7b had shortest orbit of any planet know at the time of it's discovery.

the planet CoRoT-7b is very close to it's host star so that the planet surface temperature is about 1300-1800 K.
