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.

Alpha Centauri is about 4.4 light-years (roughly 25 trillion miles, or 40 trillion kilometers) from Earth and is home to three separate stars.

This would make potential Alpha Centauri objects—if they really are somewhere in there—difficult to observe. Though, it wouldn’t be impossible.

"I think that we will reach the Alpha Centauri system, with small probes launching in the decade of the 2040s, and thus arriving in the 2060s," Eubanks said.
