The closest star to the Sun hosts a planet only a little more massive than Earth, orbiting at a distance where temperatures could in principle allow liquid water on its surface. Proxima Centauri b ...

At the speed of today’s fastest probes, reaching Proxima Centauri would take roughly 91,000 years. To make the trip possible ...

Scientists have confirmed the existence of the exoplanet Proxima b, a planet just 4.2 light-years from Earth. Given how close it is to its star, Proxima Centauri, it could have liquid water, and ...

Artist’s concept of Proxima Centauri b, an Earth-sized exoplanet orbiting the nearest star to our sun, Proxima Centauri. Now researchers think there is a second, larger planet also orbiting the star.

Proxima Centauri b is the closest exoplanet to Earth. It is an Earth-mass world right in the habitable zone of a red dwarf star just 4 light-years from Earth. It receives about 65% of the energy Earth ...

The rocky planet circling the closest star to the sun got hammered by a superpowerful flare last year, a new study reports. That's a bit of bad news for anyone hoping that the alien world, known as ...

Planets like Proxima Centauri b experience tides hundreds of times stronger than ones that move Earth’s oceans twice a day. The force of those tides also tugs on the planet’s atmosphere, but a recent ...

Astronomers using ESO telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits ...
