K2-18b, a planet outside our solar system, is eight times the mass of Earth and twice as big.

The exoplanet orbits in its star's habitable zone, at a distance that is neither too far nor too close, meaning water can exist in liquid form.

Co-author of the study, which was published in a journal named Nature Astronomy, told AFP:

This planet is the best candidate we have outside our solar system. We cannot assume that it has oceans on the surface but it is a real possibility.

Out of the 4,000 exoplanets detected to date, this is the first one to combine a rocky surface and also possess an atmosphere with water.

Most exoplanets don't have atmospheres and are giants balls of gas.

With more than 4,000 exoplanets detected, there is a future possibility that life can exist beyond the realms of planet Earth.
