WebEquation 13.8 gives us the period of a circular orbit of radius r about Earth: T = 2 π r 3 G M E. For an ellipse, recall that the semi-major axis is one-half the sum of the perihelion and the aphelion. For a circular orbit, the semi-major axis ( a) is the same as the radius for the orbit. WebOct 9, 2008 · Dwarf Planets * Negative values of rotation period indicate that the planet rotates in the direction opposite to that in which it orbits the Sun. This is called retrograde rotation. The eccentricity (e) is a number which measures how elliptical orbits are. …

WebNov 5, 2024 · The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. The third law, published by Kepler in 1619, captures the relationship between the distance of planets from the Sun, and their orbital periods. Symbolically, the law can be expressed as \mathrm {P^2∝a^3,} Web2 days ago · Various means have been proposed to deliver water to Earth after its formation.
