Kepler's harmonic law states that the distance of a planet from the Sun corresponds to the period of time it takes the planet to orbit the Sun. The formula looks like this:
p?= a3
Which statement best describes this formula summarizing Kepler's harmonic law?
• The cube of the planet's orbital radius equals the orbital period of a planet around the sun
• The square of the orbital period of a planet around the sun is proportional to the cube of the planet's orbital radius.
m
O The orbital period to the second power of a planet around the sun is proportional to the planet's orbital radius to the 1o fourth power.
O The square of the orbital radius of a planet to the sun is proportional to the cube of the planet's orbital period.
