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.
