i always thought it was 8 minutes.

anonymous · Answer

not in this problem.

anonymous · Answer

1 AU = 1.5 x 108 km = 8 light-minutes
THE ASTRONOMICAL UNIT: This is the distance between the Sun and the Earth. It is denoted by the symbol AU and it is useful when referring to the distances of planets from the Sun. 

TRY THIS OUT! :)

im still pretty lost :/

anonymous · Answer

One can define a unit of length or distance by the time it takes light to travel across it. For example, the distance traveled by light in one minute is called a light-minute. Since it takes light 8 minutes to travel from the Sun to the Earth, the distance between them is 8 light-minutes. A unit we will use more often in this course is the light-year: it is the distance traveled by light in one year.

what are you studying?
If its astronomy, I only know so much.
