Earth's approximate rate of revolution is

• 1 degree per day
• 15 degrees per day
• 180 degrees per day

Perihelion refers to the Earth being

• closer to the Sun.
• farther from the Sun.
• same distance from the Sun.

Which inference can be made about the comet's orbit when compared to Earth's orbit?

• Earth's orbit and the comet's orbit have the same distance between foci.
• Earth's orbit has a greater distance between foci than the comet's orbit.
• 
  The comet's orbit has one focus, while Earth's orbit has two foci.
• The comet's orbit has a greater distance between foci than Earth's orbit.

Which values are equal within the system?

• The distance from the Sun to the Earth is the same at point A and at point D.
• The orbital velocity of the Earth at point A equals its orbital velocity at point C.
• The gravitational force between the Earth and the Sun at point B is the same as the gravitational force at point D.
