WebDec 29, 2024 · The values for perihelion, semi-major axis, and eccentricity have far too much precision. Sedna was discovered 17 years ago, corresponding to about 0.15% of Sedna's orbital period. That's far too short of an arc length to justify five or six places of accuracy. The value for semi-major axis is inconsistent with other sources. WebJul 17, 2015 · Distance from Sun - This is the average distance from the planet to the Sun, also known as the semi-major axis, compared to Earth. All planets have orbits which are elliptical, not perfectly circular, so there is a point in the orbit at which the planet is closest to the Sun, the perihelion, and a point furthest from the Sun, the aphelion.

WebDec 30, 2024 · The time to go around an elliptical orbit once depends only on the length a of the semimajor axis, not on the length of the minor axis: (1.4.1) T 2 = 4 π 2 α 3 G M 2. The … WebTo determine the specific energy of a low-Earth orbit, we can use the equation: ξ = -μ / (2 * a) Where μ is the gravitational parameter of Earth (3.986004418 × 10^14 m^3/s^2) and a is the semi-major axis of the orbit, given by: a = (p + alt) / 2. So we can plug in the values: a = (7204 km + 912 km) / 2 = 4058 km
