A Cosmic Connection Between Star Systems 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 ...

Alpha Centauri pelts the solar system like a wet dog Wiegert and his colleague, University of Western Ontario Ph.D. student Cole Gregg, were inspired to conduct a study of these alien invaders by ...

Alpha Centauri is also moving towards us, and in some 28,000 years from now, it'll reach its closest point at a distance of a little over three light years away, raising the odds of an ...

If Alpha Centauri has an Oort cloud of distant comets as the sun does, about a million of these objects larger than a football field are now in our solar system, astronomers Cole Gregg and Paul ...

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 ...

If Alpha Centauri were to lose as much material as is assumed for our solar system, then around one million larger objects would have to have reached the Oort Cloud at the edge of the solar system ...

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 ...

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 ...

The sun could collect rogue planets and hold them at the outskirts of the solar system for millions of years, occasionally trading them with neighboring star Alpha Centauri. "Twisted Tatooine ...

Though it appears as a single bright speck in the sky, Alpha Centauri is actually a triple star system, with several suspected exoplanets, including a super-Earth called Proxima Centauri b, with more ...

Spacecraft flying by the Alpha Centauri star system could see whether the planet circling Proxima Centauri has signs of extraterrestrial life. (Image credit: Courtesy of Space Initiatives Inc.) ...
