    Question for the astronomy guys here. I know the Planets orbit around the Sun along an ellispe and not a circle. The closest approach to the Sun is called its perihelion and furthest point is called its aphelion.
    OK so my question, are the perihelions of all the planets on the same "side" of the sun or all at different points? Do they move about over time so that every so often say the Earths perihelion is close to Venus's aphelion which bring them closer then normal?
    Its a question someone asked me recently and I was stumped:confused: I thought I had a good grasp on the Solar System but I was unable to answer that one.
    Anyone???????????????????
