I am trying to solve the following problem, and I have done one step that I think is right but I don't know what I am doing, and I am very confused. 4. If Jupiter were really 7.52 A.U. from the Sun instead of 5.20 A.U., what would the affect be on the energy it gets from the Sun? What would be the affect on its appearence (size and brightness) from Earth? Careful, these are two different questions! This is what I have done thus far... I used the following equation: (apparent distance (near)/apparent distance (far)) = (distance (far)/(distance (near))^2 therefore i did: (apparent distance (near)/apparent distance (far)) =(7.52 A.U./5.20 A.U.)^2. That equals = 2.091360947. That is all I have.
