Scientists have discovered a potentially habitable Earth-like planet, located just 21 light years away, that may host liquid water on its surface.
US Scientists found that the planet, with a mass between two and three times the Earth, resides at the edge of the habitable zone of its host star Gliese 625.
They said, the discovered planet is a relatively cool star, the planet is situated at the edge of its habitability zone, in which liquid water can exist on its surface.
Researchers said, this is the sixth super-Earth closest to our solar system in the habitability zone or in goldilocks zone of its star. Goldilocks zone refers distance of a planet from a star means the planet is neither too hot, nor too cold to support liquid water, which is a key ingredient for life.
Astronomers are searching for rocky planets like ours in the Goldilocks zones of other stars. Only few rocky planets have been discovered around nearby stars.
