“Alpha Centauri (Rigil Kentaurus) is the closest star system away from our sun. It’s about 4.3 light-years away from Earth. Or another way to measure it – Alpha Centauri distance is about 25 trillion miles away! Overall, it’s about 3 times closer to the next sun-like star.” Rece...
Alpha Centauri is located just over four light years (光年), or about 25 trillion miles, from Earth. It would take today’s spacecraft more than 70,000 years to reach the star system. While this seems a very long dista...

Alpha Centauri is the closest star system to Earth and is made up of three stars and several exoplanets. We explore our stellar neighbors in more detail here.
Alpha Centauri was also the first star to have its distance measured. Thomas Henderson, a Scottish astronomer and mathematician, was the director of the Royal Observatory at the Cape of Good Hope in South Africa (between April 1832 and May 1833). Using the method of parallax he was able to...
Sending aperson to Alpha Centauri within a human lifetime wouldn't be easy. AlphaCentauri is 4.37 light-years away ? more than 25.6 trillion miles, or more than276,000 times the distance from the Earth to the sun. "Interstellartravel is extremely hard," said science fiction author and NASA...

Rigel Kentaurus is the third-brightest star in the night sky. However, its brightness is due to the proximity of the system — commonly known as Alpha Centauri — which is the sun's closest neighbor, about 4.3 light-years away from Earth. Rigel Kentaurus is part of a triple star system,...
