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 Webcustomers. To get from orbit 1 to orbit 2, the satellite must travel along an intermediate orbit called a transfer orbit, as shown in Figure 4.1.5-4. This process takes two steps, as shown in Figure 4.1.5-5. To get from orbit 1 to the transfer orbit, we change the orbit’s energy by changing the spacecraft’s velocity by an amount ∆ V 1

If we set e = 0 in the equation of the orbit, Eq. (2), we see that in a circular orbit the radius is a constant, equal to the semi-major axis,

The closer an object is to the Sun the faster it needs to move to maintain the orbit. Objects move fastest at perihelion (closest approach to the Sun) and slowest at aphelion (furthest distance from the Sun). Since planets in the Solar System are in nearly circular orbits their individual orbital velocities do not vary much. Being closest to the Sun and having the most eccentric orbit, Mercury's orbital speed varies from about 59 km/s at perihelion to 39 km/s at aphelion.
