WebThe initial eccentricity shown is that for Mercury, but you can adjust the eccentricity for other planets. The orbits are approximated by circles where the sun is off center. 4) Comets. The orbit of many comets is highly eccentric; for example, for Halley's comet the eccentricity is 0.967. In such cases, the orbit is a flat ellipse (see figure 9). Webrp is the radius at periapsis (or "perifocus" etc.), the closest distance. The eccentricity of an elliptical orbit can also be used to obtain the ratio of the apoapsis radius to the periapsis radius: For Earth, orbital eccentricity e …
