Which of the following planets does NOT have a ring around it?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Mercury.
Mercury does not have a ring around it. While Jupiter, Saturn, and Uranus each have ring systems, Mercury, being the closest planet to the Sun, lacks a ring system. Saturn is famous for its prominent and extensive rings, Jupiter has a faint ring system, and Uranus has a set of narrow rings. Mercury's lack of a ring system is due to its proximity to the Sun and the absence of sufficient material to form rings.
