In 2012, astronomers excitedly announced the discovery of Alpha Centauri Bb, the first exoplanet around our nearest neighboring star system. Here's how it all fell apart.

That star, though invisible to the naked eye, is only 4.2 light-years — about 25 trillion miles — from Earth, making it our nearest stellar neighbor. The specs of the new planet, called ...

The existence of a rocky planet named Proxima b orbiting Proxima Centauri, the closest star to our sun, has been confirmed. It is the closest exoplanet to us in the universe.

Hey neighbor! Our lonely patch of the sky just got a little less lonely with the identification of a rocky, Earth-sized planet neighboring the star closest to our own Sun.

One of the planets that orbits Proxima Centauri, the closest star to our sun, had been thought to exist within what astronomers call the Goldilocks zone. However, a new study suggests it is ...

It is a small, rocky planet not unlike our own, orbiting the sun’s closest stellar neighbor.Astronomers have long suspected that the star Proxima Centauri would be home to a planet, but proof ...

But could humans or spacecraft ever reach Alpha Centauri, the closest star system to our planet? Alpha Centauri is about 4.4 light-years (roughly 25 trillion miles, or 40 trillion kilometers) from ...

Our nearest neighboring star, Proxima Centauri, may be harboring an extensive solar system, as scientists believe they’ve found a third planet orbiting it. It’s a find that re-emphasizes just ...

Our Sun is the closest star to us, even though it is 93 million miles away. Like all stars, it is a hot, glowing ball of gas. It uses fusion to crunch 2 hydrogen atoms into 1 helium atom and a ...
