sci.planet-synodic-period Calculator
Calculates the synodic period (time between oppositions) of a planet from its sidereal period relative to Earth: 1/P_syn = 1/P_Earth − 1/P_planet. Mars has synodic period 779.9 days (≈26 months) — the Earth-Mars distance varies widely depending on orbital eccentricity at each opposition.
Inputs
Sidereal Planet Years
Time for one complete cycle (s). Period = 1 / frequency. A 50 Hz signal has a 20 ms period.
Sidereal Earth Years
Time for one complete cycle (s). Period = 1 / frequency. A 50 Hz signal has a 20 ms period.
