Kepler's Laws

Kepler's 2nd Law deals with 

• the shape of the planets' orbits
• the speed/area the planet travels 
• the length of time it takes the planet to orbit the sun

A planet moves __________ when it is farthest from the sun.

• faster
• slower

Kepler's first law states that the orbits of the planets are oval in shape or 

• ellipses
• perfect circles

The farther away a planet is from the sun, the _______ it takes it to orbit the sun once. 

• longer
• shorter

The path a planet travels around the sun is called its 

• orbit
• ellipse
• barycenter
• precession

When do planets move the fastest?

• Close to the sun
• Far away from the sun

When a planet orbits the Sun, one of the foci of the elliptical orbit is 

• the axis
• the perihelion
• the center
• the Sun

What is true about the area between points A, B and the Sun, and the area between points H, I and the Sun?

• The area between A, B and the Sun is the largest.
• The area between H, I and the Sun is the largest
• Both areas are equal in size
• There is not enough information to determine the areas

Where are the focal points located in a perfect circle?

• close together

• far apart

• on top of each other

The amount of time it takes a planet or moon to complete one revolution is its:

• Orbital Path

• Orbital Period

• Orbital Velocity
