How close is the nearest star to earth in km?

Answer 1

Olivia Aldridge

Distance to Proxima-Cenaturi = 3.995 x #10^13# km

Because of its elliptical orbit, the Sun is the star that is closest to us, at an average distance of 149 million km.

Proxima Centauri, the star closest to the Sun, is 4.25 light-years away.

1 Light-Year = 9.4 x #10^12# km

Distance to Proxima-Centauri = 4.25 x 9.4 x #10^12#

Distance to Proxima-Cenaturi = 3.995 x #10^13# km
