Suppose you could travel to Jupiter and observe changes in positions of nearby stars during one orbit of Jupiter around the Sun.

How would those changes be different from what we measure from Earth.

a. The parallax of stars, as viewed from the orbit of Jupiter, would be about twenty five times larger, since Jupiter's orbit around the Sun is about five times larger than that of Earth.
b. The parallax of stars, as viewed from the orbit of Jupiter, would be about five times smaller, since Jupiter's orbit around the Sun is about five times larger than that of Earth.
c. The parallax of stars, as viewed from the orbit of Jupiter, would be about five times larger, since Jupiter's orbit around the Sun is about five times larger than that of Earth.
d. The parallax of stars, as viewed from the orbit of Jupiter, would be about twenty five times smaller, since Jupiter's orbit around the Sun is about five times larger than that of Earth.

Answer:

c. The parallax of stars, as viewed from the orbit of Jupiter, would be about five times larger, since Jupiter's orbit around the Sun is about five times larger than that of Earth.

Explanation:

This is the statement that best describes the way in which changes in positions of nearby stars during one orbit of Jupiter around the Sun would be different from what we measure from Earth. The approximate radius of Jupiter's orbit is roughly five times larger than that of the Earth, which means that the parallax of stars, as viewed from the orbit of Jupiter, would be about five times larger. This would in turn mean that we would be able to measure parallaxes of stars that are much further away.
