The exoplanet 'Gliese 163c' has a mass of 6.9 times that of Earth and an orbital period of 26 days.
Astronomers using the European Southern Observatory HARPS telescope (or High Accuracy Radial Velocity Planet Searcher) found it orbitting a red dwarf star 49 light years away in the Dorado constellation, the Daily Mail reported.
"Gliese 163c could have a size between 1.8 to 2.4 Earth radii, depending if it is composed mostly of rock or water, respectively," researchers said.
A super-Earth is an extrasolar planet with a mass higher than Earth's, but substantially below the mass of the Solar System's smaller gas giants Uranus and Neptune.
The term super-Earth refers only to the mass of the planet, and does not imply anything about the surface conditions or habitability.
"We do not know the properties of the atmosphere of Gliese 163c but, if we assume that it is a scaled up version of Earth's atmosphere, then its surface temperature might be around 60
