Which planet is known for its seven rings made of ice particles?
A
Jupiter
B
Pluto
C
Saturn
D
Venus
Correct Answer:
C
Saturn
Saturn is the most recognisable planet in our entire solar system, famous worldwide for its spectacular ring system. Saturn has seven main rings — labeled D, C, B, A, F, G and E — that stretch hundreds of thousands of kilometres into space but are surprisingly thin, averaging only about 10 to 100 metres in thickness. These rings are primarily composed of ice particles, rocky debris, and dust ranging in size from tiny grains to chunks as large as a house. Saturn's rings are so vast and reflective that they can even be seen from Earth through a basic telescope.
- Seven Main Rings: Labeled D, C, B, A, F, G, and E from innermost to outermost — each with distinct composition and density
- Ice Composition: Rings are made up of approximately 90-95% water ice particles, with the rest being rocky material and dust
- Size: The ring system extends up to 282,000 km from Saturn's centre but is remarkably thin — only 10 to 100 metres on average
- Origin: Scientists believe Saturn's rings formed from the remains of comets, asteroids, or shattered moons that broke apart due to Saturn's powerful gravitational force
- Other Planets: Jupiter, Uranus, and Neptune also have rings — but they are much fainter, narrower, and far less spectacular than Saturn's iconic seven rings
