kepler's laws of planetary motion

Planets orbit the Sun in a shape called a(n)

• circle
• ellipse
• focus
• perihelion

An ellipse is drawn around two points called

• aphelion
• perihelion
• foci
• axis

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

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

Where is the planet moving faster

• Position A to B
• Position B to C
• Position H to I
• Position I to J

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

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

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

• longer
• shorter

When do planets move the fastest?

• Close to the sun
• Far away from the sun

• orbit

• revolution

• rotation

• cycle

When a body in space travels around a larger body in space it is said to _____________ around the larger body.

• rotate
