Question

At its closest point, Mercury is approximately 46 million kilometers from the sun. What is this distance in AU?

Answer 1

This problem can be solved using the following relation: 1 kilometer = 6.6846e-9 AU. Since we are already given the number of kilometers, we simply have to multiply it to its equivalent in AU to solve for the equivalent distance. This is done below:

46 000 000 * 6.6846e-9 = 0.3 AU
