Calculate the orbital period of a satellite or planet
📖 Orbital Period
Orbital period is the time taken for a satellite or planet to complete one full orbit around a central body. It's related to the semi-major axis through Kepler's Third Law.

💡 Tips & Information
- Orbital period is measured in seconds, minutes, hours, or days
- Formula: T = 2π × √(a³ / (GM))
- For circular orbits, semi-major axis equals orbital radius
- Earth's orbital period around Sun: ~365.25 days
- Geostationary satellites: ~24 hours (synchronous with Earth's rotation)
