hey folks,
i was wondering if anyone could give me help on a wee problem i have.
using a distance of a star of 2.6pc from earth, how would one calculate the time it took for light to be seen on Earth today...
...............
my books have rounded that 1pc = 3.3 ly
so i would take 2.6 pc to be the same as = 8.6 ly
so i believe that it would have take 8.6 lightyears for the light to reach Earth today,
how would this be converted into 'years' from light years or am i missing something?
any help would be excellent!
ta!
