Document Summary

When the sun is high in the sky, perpendicular to earth, energy is distributed over a smaller area. If the sun is low in the sky, the same energy is distributed over a larger area. Perihelion nearest point of a body"s direct orbit around the sun. Aphelion farthest point of a body"s direct orbit around the sun. The earth is closest to the sun at its perihelion about 2 weeks after the december. The earth is farthest from the sun at its aphelion about 2 weeks after the june solstice. Earth is farthest from the sun on its orbit when it is summer in the northern hemisphere. Factors that determine amount of energy received on earth sun - earth distance. The further you go, the same energy is spread over a larger area (inversely proportional to distance squared) or e~1/r^2. Earth orbits the sun in an elliptical path, which means that there is 1 point of the path when the.
