Kepler's Laws and Orbits

When a planet is closest to the sun, this is called 

• perihelion
• aphelion
• barycenter
• orbit

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 "Law of Harmonies" is which of Kepler's Laws?

• 1st
• 2nd
• 3rd
• 4th

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

This movement of earth over 11,000 years will change our north star to Vega

• nutation
• precession
• revolution
• rotation
