Kepler-10b

Kepler-10b                   All kepler series planets is discovered by kepler space telescope.Kepler-10b is first terrestrial planet discovered out side of the solar system inside the Kepler-10 system.Discovers of the planet kepler-10b are Elisa Quintana and Natalie Batalha. kepler telescope shows is presents but the planet's existence was confirmed using measurements from the W.M Keck Observatory in Hawaii. Kepler-10 system and Kepler-10b                                                 Kepler-10 star is located 560 light years away from the solar system in the Draco constellation .Age of Kepler-10 is 12 billion years which is 2 times that age of the sun.Meaning that the planet Kepler-10 is now in it's final state.kepler-10b is detected by Kepler space telescope very earlier but the planet's discovery is announced on Jan-10-2011 after 8 months data collection from kepler satellite.the planet was discovered by using transit method. 👉 light curve of kepler-10b credit:NAS

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.
