WebThis seasonal effect is reversed for the opposite hemisphere. Currently, northern summer occurs near aphelion. Milutin Milankovitch first theorized that precession and two of the Earth's other orbital parameters—eccentricity and obliquity—affected climate. Image and Animation by Robert Simmon, NASA GSFC WebThe force of earth’s gravity is the only force acting on the satellite. Not Valid; To use Newton’s 2nd Law, we must assume the mass of the satellite (and the earth’s) is not changing. Valid; The earth is spherically symmetrical with uniform density. Not Valid; The mass of the earth is much greater than the mass of the satellite. Valid

WebEarth's elliptical orbit around the Sun also factors into the length of the lunation. With an eccentricity of 0.0167, Earth's orbit is about one third as elliptical as the Moon's orbit. Nevertheless, it affects the length of the lunation by producing shorter lunations near aphelion and longer lunations near perihelion.
