Kuinka laskea Kepler Third Law
Mikä on Kepler Third Law?
Kepler's third law relates orbital period to orbital distance. It explains why planets farther from the Sun take longer to orbit.

Usein kysytyt kysymykset
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.
