Explanation: What is the closest star to our Sun? It is Proxima Centauri, the nearest
member of the Alpha Centauri triple star system. Light takes only 4.22 years to reach us
from Proxima Centauri. This small red star, captured in the center of the above image, is so
faint that it was only discovered in 1915 and is only visible through a telescope. Stars of all
types from our Milky Way Galaxy are visible in the background. The brightest star in the
Alpha Centau |
