What is Kepler's 1st law?

• The planets orbit in an ellipse

• The plants move faster when they are closer to the sun and slower when they are further from the sun

• The farther a planet is from the sun the slower the orbit

  (P² = a³)

What is Kepler's 2nd law?

• The planets orbit in an ellipse

• The plants move faster when they are closer to the sun and slower when they are further from the sun

• The farther a planet is from the sun the slower the orbit

What is Kepler's 3rd law?

• The planets orbit in an ellipse

• The plants move faster when they are closer to the sun and slower when they are further from the sun

• The farther a planet is from the sun the slower the orbit

  (P² = a³)

The point in the earth's orbit where it is closest to the sun and moves the fastest.

• aphelion/apogee

• perihelion/perigee

The point in the earth's orbit where it is farthest to the sun and moves the slowest.

• aphelion/apogee

• perihelion/perigee

Gravity is increased with...

• greater mass & shorter distance
• greater mass & farther distance
• lower mass & shorter distance
• lower mass & farther distance

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
