If 1 light year is 63,240 AU (astronomical units), how far in AUs is Alpha Centauri, which is 4.32 light years from the Earth?

If 1 light year = 63,240 AU, then 4.32 light years will equal 63,240 AU * 4.32.

##63,240 AU*4.32=273,196.8 AU##

1 AU is roughly the distance from the Earth to the Sun. But to get to Alpha Centauri you’d have to go 273,196.8 AU! That’s a long way!
