fun nextPlanetApsis(body: Body, apsis: ApsisInfo): ApsisInfo
Finds the next planetary perihelion or aphelion event in a series.
This function requires an ApsisInfo value obtained from a call to searchPlanetApsis or nextPlanetApsis. Given an aphelion event, this function finds the next perihelion event, and vice versa.
See searchPlanetApsis for more details. See planetApsidesAfter for convenient iteration of consecutive apsides.
| body | The planet for which to find the next perihelion/aphelion event. Not allowed to be Body.Sun or Body.Moon. Must match the body passed into the call that produced the apsis parameter. |
| apsis | An apsis event obtained from a call to searchPlanetApsis or nextPlanetApsis. |
