Questions & Answers
1. The two images below show the area swept out by the same planet during two separate time spans. If the first picture represents the area swept out
during a time of "A" days and the second represents the area swept out during a time of "B" days, which of the following statements is true about A and
B?
A. A > B
B. A = B
C. A < B
D. The relationship between A and B cannot be determined
Correct Answer: A. A > B
Explanation: Kepler's Second Law states that equal areas are swept out in equal times. The area shaded in the first picture is greater than the area
shaded in the second picture, so it must represent a longer period of time.

2. Earth travels fastest in January and slowest in July. What is the most likely explanation for this?
A. Earth is nearest the Sun in July and farthest away in January.
B. Earth is nearest the Sun in January and farthest away in July.
C. Earth is nearest the Sun in April and farthest away in October.
D. Earth is nearest the Sun in October and farthest away in April.
Correct Answer: B. Earth is nearest the Sun in January and farthest away in July.
Explanation: According to Kepler's Second Law, a planet travels fastest when it is nearest its sun. This means that Earth is actually closest to the
Sun in January, when it is winter in the northern hemisphere! Because Earth's orbit is nearly circular, the changing distance between Earth and the
Sun has very little influence on seasonal changes. Seasons are caused by the tilt of Earth's axis.

3. Earth's orbit is a nearly circular ellipse with the Sun at one focus. How would its orbit change if Earth were twice as massive?
A. The orbit would still be an ellipse, but the Sun would now be at the center of the ellipse.
B. The orbit would become a much flatter, more eccentric ellipse.
C. Earth would fly off into space, never to return.
D. The orbit would not change at all.
