Problem: "In the early 1600s, Johannes Kepler established three laws of planetary motion. According to Kepler's third law, the orbital period of a planet, measured in Earth years, is related to its distance from the Sun in astronomical units. One astronomical unit (AU) is defined as the average distance from the Sun to Earth-93 million miles, or 150 million kilometers. The law states that a planet's orbital period squared is equal to its mean solar distance cubed: p2=d3. Applying Kepler's third law, what would be the period of revolution of a hypothetical planet that is 4 AUs from the Sun? Show your calculation in the following space."
