PARIS — A rocky world orbiting a nearby star has been confirmed as the first planet outside our solar system to meet key requirements for sustaining life, scientists said on Monday.
Modelling of planet Gliese 581d shows it has the potential to be warm and wet enough to nurture Earth-like life, they said.
It orbits a red dwarf star called Gliese 581, located around 20 light years from Earth, which makes it one of our closest neighbours.
