Synodic Period Calculator
Calculate the synodic period between two orbiting bodies
📖 Synodic Period
The synodic period is the time between successive conjunctions (when two bodies appear in the same direction) as seen from a third body. It's different from the orbital period due to relative motion.

💡 Tips & Information
- Synodic period is measured in days or years
- Formula: 1/S = |1/P₁ - 1/P₂|, where S is synodic period, P₁ and P₂ are orbital periods
- Moon's synodic period: ~29.5 days (new moon to new moon)
- Mars synodic period: ~780 days (opposition to opposition)
- Synodic period is always longer than the shorter orbital period
