Question

Which is always true about the distance of a planet from the Sun?

a. The farther from the Sun, the shorter a planet’s revolution.
b. The farther from the Sun, the longer a planet’s revolution.
c. The farther from the Sun, the shorter a planet’s rotation.
d. The farther from the Sun, the longer a planet’s rotation.

Answer 1

The answer is B. A planet distant from the sun has a longer elliptical path around the sun that one closer to the sun. An analogy is that if you draw a circle with a larger diameter (straight distance from sun as center to the planet) then the bigger the diameter of the circle (elliptical path).
