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

• ellipses
• perfect circles

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

An ellipse is drawn around two points called

• aphelion
• perihelion
• foci
• axis

Where is the planet moving faster

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