Final answer:
The true statement about Pluto is that it is orbited by Charon. Charon is a large moon relative to Pluto, making it an interesting system where both bodies are tidally locked. Pluto orbits the Sun every 248 Earth years and does not orbit between Uranus and Neptune.
Step-by-step explanation:
Of the statements given about Pluto, the true one is that Pluto is orbited by Charon. Charon is indeed a substantial moon, with a diameter of about 1,200 kilometers, which is more than half the size of Pluto itself. This size relationship makes Charon the moon with the largest size relative to its parent planet, leading to considerations of Pluto and Charon as a sort of double world system. Charon is not in a retrograde orbit; rather, Charon and Pluto are tidally locked, meaning they always show the same face to each other. As for the orbital period, Pluto takes about 248 Earth years to complete one orbit around the Sun, not 14 months. Pluto does not orbit between Uranus and Neptune; it has a more eccentric and inclined orbit, which only occasionally brings it closer to the Sun than Neptune.
