Alpha Centauri is racing toward us at 0.007 light-years per century (80,000 kilometers per hour) and will be closest 28,000 years from now, when it will be 3.2 light-years from Earth.

The rocky planet slightly larger than Earth orbits Proxima Centauri, a red dwarf that's part of a triple-star system called Alpha Centauri, an international team of scientists announced in the ...

A recent study suggests that the Alpha Centauri system, our stellar neighbor, could be their source. Interstellar objects, such as asteroids or comets, are not gravitationally bound to a star.

Alpha Centauri, the closest star system to Earth, is moving toward us at 79,000 kilometers per hour (49,709 mph). It won’t reach its nearest point for another 27,700 years, but some of its ...

This image of the sky around the bright star Alpha Centauri AB also shows the much fainter red dwarf star, Proxima Centauri, the closest star to the Solar System. This image was created from ...

Our nearest stellar neighbor, Alpha Centauri, is moving towards us at a slow and steady pace. In about 3,000 years, the triple star system will be at its closest point to Earth, but new research ...

At times Proxima Centauri is approaching Earth at about 5 kilometres per hour — normal human walking pace — and at times receding at the same speed. This regular pattern of changing radial ...

The tiny spacecraft would first need to approach the star Alpha Centauri A as close as around four million kilometres, corresponding to five stellar radii, at a maximum speed of 13,800 kilometres ...
