Question

Kepler also discovered a relationship between the time it takes planets to orbit the Sun and their relative distances from the Sun. The planet’s orbital period (P ), is the time it takes to travel once around the Sun (in Earth years). A planet’s semi-major axis (a) is its average distance from the Sun in AU. This relationship is known as Kepler’s third law, and says that a planet’s orbital period (P ) squared is proportional to the semi-major axis (a) cubed: 𝑃! = 𝑎" Is this a linear relationship? (Circle one) Yes No
