Kepler's 3rd laws states that the semi-major axis of a planet’s orbit (average distance to the sun in A.U.’s) is related to the planet’s orbit period by the equation:

p² = a³

In this equation what does 'p' represent?

• A planet's average distance from the sun

• A planet's orbital period

Kepler’s 3^rd law states that the semi-major axis of a planet’s orbit (average distance to the sun in A.U.’s) is related to the planet’s orbit period (in Earth-years) by the equation:

p² = a³

What does 'a' represent in this equation?

• A planet's distance from the sun

• A planet's orbital period

Kepler's 3rd law states that a planet's period is proportional to its distance from the sun. Use the calculator found at http://www.1728.org/kepler3.htm to solve the following problem:

Mercury's period (p) is 0.241 years, how far is it from the sun (a)? Your answer should be in AUs. Do NOT include units in your answer.
