Does Uranus Have Rings? The Surprising Answer!

Last Updated on

As one of the most distant planets in our system, Uranus is a peculiar ball to be unraveled. Originally discovered back in 1781 by William Herschel, our seventh planet appears to have a circular silhouette that goes up vertically around it, unlike Saturn, whose rings are horizontal in their position and are more visible.

That being said, Uranus does have rings. There are two separate layers of these discs in total, both of which will be described in detail below.

How Many Rings Does Uranus Have?

Although some of the rings of this planet are far apart, there are a total of 13 rings, which are divided into two sections; the outer and inner rings.

There are two outer rings—one is a reddish color and the other is a vibrant blueish color. There are also nine inner rings that are much thinner and have a gray, dark tone. A few are hard to see due to their faintness. These also have names, which from the farthest to closest can be seen as listed here: Mu, Nu, Epsilon, Lambda, Delta, Gamma, Eta, Beta, Alpha, 4, 5, 6, and Zeta. 

How Did They Form and Why Are They Vertical?

It’s estimated that the rings of Uranus were created when ancient moons crashed into each other and left their debris floating in space. Afterward, the gravity of Uranus pulled them into orbit and formed a ring-like phenomenon. Since the planet’s poles are on its sides and rotate vertically, the ring followed suit and ended up in a position that looks a bit unconventional. There is a slight tilt to it, but it can be hard to see from some angles. Still, the rings are beautiful in their own respect!

When Were the 13 Rings Discovered?

It wasn’t until recently that the discs surrounding Uranus were found. Astronomers at the Kuiper Airborne Observatory confirmed the existence of these rocky, icy rings back on March 10 in 1977. However, it wasn’t until around 2005 that all the rings had been fully revealed from high-resolution Hubble Telescope images.

What are Uranus’s Rings Made Of?

The rings that orbit Uranus are composed differently based on their location. The outer ring is made of massive, icy rocks, but the inner rings are darker and have a smaller size even though they are also made of rock and ice. Some of these rings reflect very little light due to their extremely dark hues.

Are Uranus’s Rings Visible?

Unfortunately, the rings of Uranus cannot be seen without high-end scientific equipment. You definitely won’t be able to see them with the naked eye and, sadly, even most telescopes won’t be able to catch sight of this fascinating feature either. You would need something pretty powerful to see the planet because even at its closest distance to us here on Earth, it’s still a whopping 1.6 billion miles (2.6 billion kilometers) away.
