The planet, KOI-314c, is 60 percent larger than Earth but has the same weight.
It is also much hotter than Earth, with scientists saying that its surface temperatures would be around 104 degree Celsius.
KOI-314c is suspected to have a gaseous atmosphere, making the planet just 30 per cent denser than water, Sky News reported.
However, lead astronomer Dr David Kipping, from the Harvard-Smithsonian Centre for Astrophysics in the US, said that the planet is certainly not Earth-like.
