Planets orbit the sun in a shape called an ellipse.

• Kepler's 1st Law

• Kepler's 2nd Law

• Kepler's 3rd Law

Planets travel faster when they are closer to the sun.

• Kepler's 1st Law

• Kepler's 2nd Law

• Kepler's 3rd Law

When do planets move the fastest?

• Close to the sun

• Far away from the sun

Kepler's 1st Law says this about the orbits of planets

• they are elliptical.

• they are perfect circles.

• they are always perfect polygons (square, pentagon, hexagon, etc.,)

• they are parabolic.

Kepler's 3rd Law states that the farther away a planet is from the sun, the _______ it takes it to orbit the sun once (year).

• longer

• shorter

According to Kepler's 2nd Law when do planets move the fastest?

• Close to the sun

• Far away from the sun
