WebDec 21, 2024 · The orbital eccentricity is a parameter that characterizes the shape of the orbit. The higher its value, the more flattened ellipse becomes. It is linked to the other two important parameters: the semi-major axis and semi-minor axis (see figure below), with the following eccentricity formula: e = \sqrt {1 - b^2/a^2}, e = 1 − b2/a2, where: WebJul 9, 2015 · The orbit isn't changing, yet the 'constant' values I'm calculating are. I've been reading this and others such as this. I first calculate the angular momentum with h → = r → × v →. This value changes as the planet goes around the orbit. Then I calculate the eccentricity with e → = ( v 2 − μ / r) r → − ( r → ⋅ v →) v → μ
