Neptune Rings: Composition, Discovery, and Interesting Facts

KOMPAS.com – Neptune is one of four planets in the Solar System that have rings. Neptune was only discovered in 1846 and its rings were only discovered for certain in 1989 by the Voyager 2 probe.

In fact, Neptune’s first ring was discovered in 1968, but scientists were unable to determine whether it was a complete ring.

What are Neptune rings made of?

Neptune has five rings, namely Galle, Le Verrier, Lassell, Arago, and Adams. The rings are named after astronomers who made important discoveries regarding this planet.

Neptune’s rings consist of at least 20% dust and some rings contain as much as 70% dust. Meanwhile, the remaining materials that make up Neptune’s rings are small rocks.

Neptune’s rings are difficult to see because they are dark and vary in density and size. Astronomers think Neptune’s rings are younger than the planet’s age, and were likely formed when one of Neptune’s moons was destroyed.

Neptune’s innermost ring orbits at a distance of 41,000 km from the planet, and is up to 2,000 km wide.

6. Neptune’s rotation period is 16.11 hours.

7. The equatorial diameter of Neptune measured at a pressure level of one bar is 49,528 km.
