Kepler's third law relates orbital period to orbital distance. It explains why planets farther from the Sun take longer to orbit.
सूत्र
The calculator applies T² = (4π² / GM) × a³

अक्सर पूछे जाने वाले प्रश्न
Does Kepler's law apply to all objects?
Yes, it applies to any orbit around a massive central body, from planets around stars to satellites around planets.
Why is period proportional to distance to the 3/2 power?
Gravity weakens with distance, requiring slower speeds at greater distances, which more than compensates for longer path length.
