Distance to next solar system

What is the closest star system to Earth?

For example, the nearest star system to ours is the triple star system of Alpha Centauri, at about 4.3 light years away. That's a more manageable number than 25 trillion miles, 40 trillion kilometers or 272,000 AU. Light years also provide some helpful perspective on solar system distances: the Sun is about 8 light minutes from Earth.

Which star is closest to the Sun?

Of the three stars in the system, the dimmest - called Proxima Centauri - is actually the nearest star to the Sun. The two bright stars, called Alpha Centauri A and B form a close binary system; they are separated by only 23 times the Earth - Sun distance. This is slightly greater than the distance between Uranus and the Sun.

How far away is the Sun from Earth?

That's a more manageable number than 25 trillion miles, 40 trillion kilometers or 272,000 AU. Light years also provide some helpful perspective on solar system distances: the Sun is about 8 light minutes from Earth. (And yes, there are also light seconds!)

Why is Proxima the closest star to the Sun?

That’s because it’s part of the Alpha Centauri system, the closest star system to our sun. Alpha Centauri consists of three known stars (including Proxima). Of the three, Proxima is closest, at 4.2 light-years away. Alpha Centauri appears as the 3rd-brightest star in Earth’s sky. But Proxima is too faint to see with the eye.
