One of the three stars in Alpha Centauri is Proxima Centauri, which is the nearest star to the Earth, except of course for the Sun. The name “Proxima” comes from a Latin word which means “close.” Even though Proxima Centauri is the closest star to the Earth outside of our solar system, it is not really close.

A person traveling in a modern spacecraft would not arrive at Proxima Centauri within this lifetime or the next, or even ten lifetimes because the distance is so great.

Alpha Centauri is a triple-star system. One of the three stars in Alpha Centauri is Proxima Centauri, which is the nearest star to the Earth, except of course for the Sun. The name “Proxima” comes from a Latin word which means “close.”

Even though Proxima Centauri is the closest star to the Earth outside of our solar system, it is not really close. Interstellar distances are so large that they are almost impossible to imagine. A person traveling in a modern spacecraft would not arrive at Proxima Centauri within this lifetime or the next, or even ten lifetimes because the distance is so great.
