The Sun is the closest star to Earth.

Proxima Centauri, which is part of the Alpha Centauri star system, is the second nearest star at a distance of 4.24 light-years from Earth.

(B) Sirius – The brightest star in the night sky, about 8.6 light-years away.

(D) Alpha Centauri – A star system that includes Proxima Centauri, but the two main stars (Alpha Centauri A & B) are farther than Proxima Centauri.
