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.

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:

A planet is 3.9 AU from the Sun. Find the period of the planet (p) in years. Do NOT include units in your answer.

Kepler's 1st law says that the eccentricity of a planet's orbit can be determined with the following equation e=f/d

If the focal length of an ellipse is 2 and length of its major axis (d) is 5, what is the eccentricity (e) of the ellipse?

At which point of the orbit will the planet have the lowest velocity?

• A to B

• C to D

• F to G

• L to A
