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

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

What has an eccentricity of zero

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

The areas swept by an invisible line between the sun an the earth will be
