Hello again: In light of Luke's very clear and informative explanation of how a planet's orbit and the inclination of its axis affect the shape of the analemma and EOT curves, what would the analemma look like if the orbit were a perfect circle and there was no tilt to the axis? Would the analemma be a straight vertical line, a point, or would it simply disappear? And would the EOT curve turn into a horizontal line with a value of zero?
Thanks again, John Carmichael
