#~~267# thousand AU

Forgeting the Sun which is 1 AU from us, we have Proxima Centauri at 4.23 light-years from us.

4.23 light years is:

#4.23 year xx 365*24*60*60 (seconds)/year xx 300000 (km)/(second)#

#=4.0xx10^13 km#

#1 AU=1.496xx10^8 km#

So the distance of Proxima Centauri in AU is

#=(4.0xx10^13)/(1.496xx10^8)#

#~~267# thousand AU
