Two new Earth-like planets have been found orbiting one in all our closest neighbouring stars, they usually could possibly be able to supporting life.

“Teegarden’s star” is simply about 12.5 gentle years away from Earth and is without doubt one of the smallest recognized stars. It’s about 2,700 °C heat and about ten instances lighter than the Solar. 

Now knowledge collected by a world analysis group led by the College of Göttingen clearly reveals the existence of two planets orbiting the star.

And excitingly, they’re positioned within the so-called “liveable zone” the place water might be current in liquid type.

The astronomers suspect that the 2 planets could possibly be half of a bigger system.

“Many stars are apparently surrounded by techniques with a number of planets,” explains co-author Professor Stefan Dreizler of the College of Göttingen.

Teegarden’s star is the smallest star the place researchers have thus far been in a position to measure the burden of a planet straight.

Though planetary techniques round related stars are recognized, they’ve at all times been detected utilizing the “transit technique”.

This requires planets to go visibly in entrance of the star and darken it for a second, which solely occurs in a really small fraction of all planetary techniques.

The 2 planets are positioned throughout the liveable zone round Teegarden’s Star.


Such transits haven’t but been discovered for the brand new planets.

Nevertheless, the system is positioned at a particular place within the sky, which implies that from Teegarden’s star you possibly can see the planets of the photo voltaic system passing in entrance of the Solar.

“An inhabitant of the brand new planets would due to this fact have the chance to view the Earth utilizing the transit technique,” says Reiners.

The brand new planets are the tenth and eleventh found by the group.

The outcomes have been revealed within the journal Astronomy and Astrophysics .
