What is the definition of eccentricity in relation to orbits?

Back

Eccentricity is a measure of how much an orbit deviates from being circular. It ranges from 0 (perfectly circular) to 1 (parabolic).

What is Kepler's 3rd Law of planetary motion?

Back

Kepler's 3rd Law states that the square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. This means that planets further from the Sun take longer to orbit.
