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.
