Synodic Period Calculator — Formula
## Synodic Period
The synodic period is the time between identical relative configurations of two orbiting bodies.
### Formula
**1/P_syn = |1/P1 - 1/P2|**
where P1 and P2 are the sidereal orbital periods.

Exemplo Resolvido
Find the synodic period of Mars as seen from Earth.
- 1/P_syn = |1/365.25 - 1/687|
- = |0.002738 - 0.001456| = 0.001282
- P_syn = 1/0.001282 ≈ 780 days ≈ 2.14 years
