As of June 2014, the closest known star to the Sun is Proxima Centauri. Proxima Centauri is located 4.24 light-years away from the Sun.
Proxima Centauri, at about 4 light years, is the closest star after the Sun, followed immediately by the binary stars Alpha Centauri A and B. Proxima Centauri is thought to orbit the Alpha Centauri system in an extremely wide orbit. Theoretically there could be some as-yet-undiscovered small red dwarf or brown dwarf closer to the Sun than Proxima Centauri.
I think that proxima centauri is approximately 4 light years away from the sun. One light year is equal to 5,865,696,000,000 miles. So, 5,865,696,000,000x4 = 23,462,784,000,000 Proxima Centauri is approximately 23,462,748,000,000 miles away from the sun.
The next closest is a red dwarf star called Proxima Centauri, much further away. The sun is around 8 minutes away at the speed of light, while Proxima Centauri is around 4.2 years away at the speed of light (light years).

Proxima Centauri _IS_ a sun.
As the closest star to our sun, Proxima Centauri is in our galaxy.
The closest star to earth is the sun. The next closest is a red dwarf star called Proxima Centauri, much further away. The sun is around 8 minutes away at the speed of light, while Proxima Centauri is around 4.2 years away at the speed of light (light years).
As of June 2014, the closest known star to the Sun is Proxima Centauri. Proxima Centauri is located 4.24 light-years away from the Sun.
The closest star system to our Sun is Alpha Centauri, which consists of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Proxima Centauri is the closest to the Sun at a distance of about 4.24 light-years.
The nearest star to Earth is Proxima Centauri (Alpha Centauri C).
Proxima Centauri, at about 4 light years, is the closest star after the Sun, followed immediately by the binary stars Alpha Centauri A and B. Proxima Centauri is thought to orbit the Alpha Centauri system in an extremely wide orbit. Theoretically there could be some as-yet-undiscovered small red dwarf or brown dwarf closer to the Sun than Proxima Centauri.
Alpha Centauri
I think that proxima centauri is approximately 4 light years away from the sun. One light year is equal to 5,865,696,000,000 miles. So, 5,865,696,000,000x4 = 23,462,784,000,000 Proxima Centauri is approximately 23,462,748,000,000 miles away from the sun.
Proxima Centauri is about 0.005% as bright as the sun. In other words the sun is about 20,000 times brighter than Proxima Centauri.
The next closest is a red dwarf star called Proxima Centauri, much further away. The sun is around 8 minutes away at the speed of light, while Proxima Centauri is around 4.2 years away at the speed of light (light years).
Proxima Centauri is 4.243 light years away, or 2,231,648 light minutes.
