When viewed from Earth,which of the following planets shows the GREATEST change in angular size over one planetary orbit?

Question

Quizplus · Accepted Answer

Venus has the shortest orbital period of about 225 Earth days and is also the closest planet to Earth, which means that it undergoes the greatest change in angular size during one planetary orbit. This is because the apparent size of a planet is directly proportional to its distance from Earth, and Venus comes closest to Earth during its inferior conjunction, which occurs about every 584 days. During this time, Venus appears as a large "dazzling star" in the evening or morning sky, which is why it has been known as the "Morning Star" or the "Evening Star" in ancient times. In contrast, Mercury has a longer orbital period but is much smaller and farther away, while Uranus has a longer orbital period and a smaller apparent size due to its greater distance from Earth. Jupiter has a relatively large apparent size but its orbital period is much longer than Venus, so it does not show as much variation in angular size over one planetary orbit.
