Half of the major axis is termed a semi-major axis. The equation for Kepler’s Third Law is P² = a³, so the period of a planet’s orbit (P) squared is equal to the size semi-major axis of the ...

Kepler’s second law says that a line joining a planet and ... and the orbit’s semi-major axis in astronomical units, the equation simplifies to period squared equals semi-major axis cubed.

Johannes Kepler was a 16th century astronomer who established three laws which govern the motion of planets around the sun. These are known as Kepler’s laws of planetary motion. These laws ...

In tests, the AI tool was able to re-discover fundamental scientific equations like Kepler's third law of planetary motion. (NASA/JPL) Humans are no longer the only ones capable of making ...
