Okay, I have to do this for my grade 9 science but I missed the day we learned it and have no idea what to do? This is what we have to do

But I don't understand it, could somebody please help me with this? Possible by doing the first three or something (Earth, Sun, Mercury) (and putting the information on that sheet I posted above, also on the side showing the calculations)

I am not expecting you to do this as homework for me but just the first few so I understand how to do it etc and then I can do the rest. THANKS SO MUCH.
