š” Tips & Information
- Synodic period is measured in days or years
- Formula: 1/S = |1/Pā - 1/Pā|, where S is synodic period, Pā and Pā 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
