The diagram below represents the position of Earth in its orbit and the position of a comet in its orbit around the Sun.
Which inference can be made about the comet's orbit, when it is 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 a greater distance between foci than Earth's orbit.
The comet's orbit has one focus, while Earth's orbit has two foci.

Question 5
5.
Which statement describes the motion of Earth around the sun?
The speed of Earth is constant because the distance remains the same between Earth and the sun.
Speed increases the farther Earth is from the sun and decreases the closer it is to the sun.
The speed of Earth is constant regardless of its distance from the sun.
Speed increases the closer Earth is to the sun and decreases the farther it is from the sun.
