Category:History of computing hardware Category:History of computing in the United StatesQ: Explanation for a discrepancy between Earth's position and the Sun's position This source has a diagram of the Earth's orbit and the Sun's position. I'm assuming that it's drawn by someone who understands the math, but I'm a bit confused about what's happening. The Sun is apparently at the following positions: When it's closest to the Earth (southern summer solstice): [12 degrees] When it's furthest from the Earth (northern winter solstice): [54 degrees] Since Earth orbits the Sun, the Earth's position is also: When it's closest to the Sun (southern summer solstice): [90 degrees] When it's furthest from the Sun (northern winter solstice): [270 degrees] These positions imply that (as seen from the Earth) the Sun is at about [168 degrees] at the summer solstice, which implies that (as seen from the Sun) the Earth is about to move backwards into the Sun (like a train of cars driving backwards). What's happening here? A: The source that you link to appears to be drawing an Earth-centered system. The Earth is fixed to the center of the coordinate system, and everything else rotates around the Earth. So, when you are talking about "when the Earth is at (x,y)", you are talking about what the Earth is doing relative to a coordinate system that is fixed to the Earth. The coordinate system is rotating relative to the Sun. See the diagram on Wikipedia: A: The Earth does not actually move in and out of the Sun at the solstices - that's what you are getting confused about. In a geocentric coordinate system, which the Earth-centered diagram uses, the Earth remains fixed and the other objects move around it. At the summer solstice the Earth is at the northernmost point of its orbit around the sun and everything else revolves around the sun. In a geocentric coordinate system the Earth is at the origin and the sun is at the point (0,0) so the planets are moving away from it and towards the north pole of the Earth. At the solstice, Jupiter and Venus
