# Question: Kepler s law of planetary motion says that the square of

Kepler's law of planetary motion says that the square of the period of a planet (T2) is proportional to the cube of the distance of the planet from the Sun (r3). Mars is about twice as far from the Sun as Venus. How does the period of Mars compare with the period of Venus?
