Homework Help: Science

Posted by Sara on Monday, February 22, 2010 at 9:21pm.

Y r the distances to the planets given in km, while the distances to stars & galaxies r given in light years?

I am really stumped on this quest. I think because the universe is so huge that it would be way too dificult to measure distances to stars and galaxies in km.

Your help will be appreciated, thanks
