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

• ellipses.
• perfect circles.
• squares.
• triangles.

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

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

The place where a planet is closest to the Sun as it orbits the Sun is called the

• perihelion.
• aphelion.

The place where a planet is farthest away from the Sun in its orbit around the Sun is called the

• aphelion.
• perihelion.

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

• faster
• slower
