Planets similar to Jupiter's size is called Corot-9b orbiting distant stars within the Milky Way galaxy every 95 days.
Scientists believe that the planet could be the Rosetta Stone or research liaison with other eksoplanet help understand the galaxy.
Dr Hans Deeg, one of the scientists from the Institute of Astrophysics said, "Corot-9b is the first eksoplanet closely resembles the planet Earth in the solar system. Having the same size of Jupiter and orbits similar to Mercury.
Successfully detected the planet using the COROT space telescope by the French space agency, CNES.
More than 400 eksoplanet have been found recently, but most of those called by the term 'hot Jupiter', with gas giants who embraced their main stars and has a surface temperatu of about 1000 degrees Celsius or more.
Approximately 70 eksoplanet been found by using different methods depending on the planet through the star in front of him, or called a transit. Planet release himself by sucking out some of the starlight that caused the planet to be dim.
Corot-9b identified by using the transit method. Planet take 8 hours to cross in front of its star, which provides plenty of information to astronomers.
But the planet is turned into a special because the planet is not a hot Jupiter. By relying on the presence of reflective clouds in the atmosphere, surface temperatures between minus 20 and 160 degrees Celsius.
Dr. Didier Queloz of the University of Geneva in Switzerland and coauthor of the research published in the journal Nature says, "Our analysis provides more information about the Corot-9b than other eksoplanet the same type."
"The discovery could open new research areas to better understand the atmosphere in a more moderate and the planet with a low temperature, and in particular a new perspective to understand the complete low-temperature chemistry in space." Add Queloz.
Dr Claire Moutou of France Marseille Astrophysics Laboratory, other members of the international team of 60 people say, "These findings will be binding for the Rosetta Stone eksoplanet research."
Planet is found by using the Corot in 2008, at the La Silla observations Institute of Chile, following the earlier discovery by viewing the details of the star system.
By using an instrument called the harp through the measurement of light waves they confirm that Corot-9b is a great eksoplanet with approximately 80% of Jupiter.
