Summary
[edit]- Description:
Deutsch: Vergleich zweier verschiedener Definitionen des tropischen Jahres (von Frühlingsäquinoktium zu Frühlingsäquinoktium, bzw. Zeit, welche die mittlere Sonne für 360° auf der Ekliptik braucht) mit der Länge des Gregorianischen Kalenderjahres.
English: Comparing two different definitions of the tropical year (from spring equinox to spring equinox, and time needed by the mean sun for 360° on the ecliptic) with the length of the Gregorian calendar year.
- Source: drawn by myself, using the orbital data provided by J. Meeus: More Mathematical Astronomy Morsels, Willmann-Bell 2002, chapter 63 (and due to Simon et al., 1994). The "360°" curve is the reciprocal of the instantaneous rate of change of the sun's mean longitude, expressed in ephemeris days per 360°. The green curve is the time interval (expressed in ephemeris days) needed by the sun's ecliptical longitude (calculated from the mean orbital elements) for one full revolution, starting and ending at the spring equinox.
