surender gupta dunar amazing facts online In August, astronomers announced they'd detected a planet 1.3 times the mass of the Earth orbiting Proxima Centauri, just 4.2 light years away. The planet, called Proxima b, sits in the so-called Goldilocks zone of the faint red dwarf star, where the average surface temperature of the planet is not too hot, nor too cold, to harbour liquid water.
It's been a bumper few years for "exoplanets" – planets orbiting distant stars – but we will never find a closer one than this.
Astronomer Paul Butler from the Carnegie Institute of Washington said: "What Proxima b does is act like a neon sign: right here, folks, this is not fuzzy or vague, it's the very nearest star in the sky."
