Exoplanet could contain Water – Kepler-62f 
Researcher doing some research on dubbed Kepler-62f, has a diameter 40 percent larger than that of Earth,

They came up with great news. Here is what they found

”An Exoplanet can have Water “ Researchers said. It means there may also have Carbon and oxygen present in atmosphere. The only codition for water is planet atmosphere should be warm it.
They also said that “high carbon-dioxide atmosphere is a reliable way to put liquid water on this planet,” Aomawa Shields, a scientist at the University of California, Los Angeles, he is involved in the new research aid at the Astrobiology Science Conference in Chicago in June.

Kepler-62 is a small, dim star two-thirds the size of the sun and only one-fifth as bright. Five planets orbit the star, which lies 1,200 light-years from the sun in the constellation Lyra.Only two planets lie in the habitable zone, which liquid water could lie on the surface of a planet.
Water is main ingredient for evolution of life. Two Planets present in Kepler-62 are considered as Super Earth — rocky exoplanets (Super Earth are larger then Earth ). When it was discovered, Kepler-62f was the most Earth-like planet known, in terms of size and orbit.
Kepler-62f present at farther from it’s sun. It is the farthest out of the five planets known to orbit the star. which it circles once every 267.3 Earth days.

Shields put the planet into a simulation with an Earth-like rotation and a carbon-dioxide atmosphere. She then studied it with different obliquities — in other words, the angles at which it tilts in respect to the sun. In one case, the planet boasted an Earth-like obliquity of around 23 degrees, while in another, it had a sharper tilt of 60 degrees. Both scenarios resulted in the freezing of surface water, creating an icy snowball planet.

Kepler-62f lies farther from its sun — in fact, it is the farthest out of the five planets known to orbit the star, which it circles once every 267.3 Earth days.
