He also showed me this: 1.8668509 x 10-6 pc After searching a bit I've learned that the minimum distance from the Earth to Mars is about 54.6 million kilometres, but my friend says that the answer is not correct and that I have to look to the "formula?" he showed. I ask you to give me a hand on this one, because I'm stuck... Thank you!
