Which is the nearest star to Earth other than Sun?

The two main stars are Alpha Centauri A and Alpha Centauri B, which form a binary pair. They are an average of 4.3 light-years from Earth. The third star is Proxima Centauri. It is about 4.22 light-years from Earth and is the closest star other than the sun.

Moreover, where is the nearest star to Earth?

The nearest stars to Earth are in the Alpha Centauri triple-star system, about 4.37 light-years away. One of these stars, Proxima Centauri, is slightly closer, at 4.24 light-years.

How far is the nearest star to the Earth?

The inner binary appears to the unaided eye as a single star, the third brightest in the night sky, but it lies 4.37 light years from the Sun. Faint Proxima Centauri is the one that claims the honor of being our true nearest stellar neighbor at only 4.24 light years away.
