Astronomers have discovered one of the lightest planets ever found and it's orbiting the star right next door to our own, just over four light-years away from Earth. Confirmation of Proxima d is ...

A team of astronomers have discovered evidence for yet another exoplanet orbiting Proxima Centauri, our closest neighboring star just over four light-years away. The planet, dubbed Proxima d, is the ...

Astronomers may have detected a new exoplanet around Proxima Centauri, the star closest to our solar system. This tiny new world is one of the lightest ever discovered, which is even more impressive ...

A new planet has been discovered in our closest planetary system. It’s only 25% the mass of Earth and likely isn’t habitable. The new planet is the third planet that’s been found in its planetary ...

A little over four light-years away is Alpha Centauri, the closest star system to the Sun. And in August 2016, researchers announced they’d found a long-searched-for planet around Proxima Centauri, ...

A third planet has been detected orbiting the closest star to our solar system, Proxima Centauri. With a mass one-quarter that of Earth, the planet – known as Proxima d – is one of the lightest ...

The sun’s nearest neighbor may actually host three planets, a new study reports. Astronomers have found evidence of a third planet circling Proxima Centauri, a red dwarf star that lies a mere 4.2 ...
