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

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

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

What has an eccentricity of zero

• a straight line
• a large ellipse
• a circle
• a small ellipse

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

• faster
• slower
