Synodic Period Calculator — Frequently Asked Questions
Q1 What is the difference between sidereal and synodic periods? ▾
Sidereal period is the true orbital time around the Sun relative to fixed stars; synodic period is the time between successive identical alignments as seen from Earth (e.g. conjunctions/oppositions).
Q2 Why are Mars launch windows spaced 26 months apart? ▾
The synodic period between Earth and Mars is ~780 days (25.6 months); launch windows align only when Earth catches up to Mars.
