![]() The study was published in the journal Nature. Now astronomers have to either rethink the Roche limit or come up with another explanation for the existence of Quaoar's ring. By not having done that, the ring has breached what astronomers call the Roche limit, the first known ring around a celestial body to have done so. Instead, it should coalesce under its own gravity and form another moon, just like Weywot. With a radius of about 2,420 miles (3,885 km) from Quaoar's center, the ring is too far away from the dwarf planet that its gravity should no longer be able to keep the material dispersed. In fact, before astronomers discovered Quaoar's ring in observations from several telescopes conducted between 20, they had thought that it was impossible for a ring to exist at such a distance. Quaoar's ring is at a very unusual distance from its parent body. And a recent observation campaign revealed that it also has a ring of material in its orbit. Residing in the Kuiper Belt, the doughnut-shaped ring of rocky and icy debris in the outer solar system, Quaoar is a proud owner of its own moon, the 100-mile-wide (160 km) Weywot. Scientists have been on the lookout for a planet orbiting three stars, and found potential evidence in another system, GG Tau A, located about 450 light years from Earth. Everything in this galaxy ring is housed in a scratch-resistant and durable black ceramic. It was not until almost 50 years later that the astronomer Christian Huygens discovered that the shapes were really rings. Its vivid depiction of outer space is perfect if youre looking to add something special to your jewelry collection. This planet has the most visible rings - Saturn. Discovered in 2002 and about 697 miles wide (1,121 kilometers), Quaoar is one of the so-called trans-Neptunian objects, small planets orbiting beyond the solar system's outermost planet Neptune. The Deep Space Ring includes malachite and amethyst are combined with a four-color glow powder combination to make a stunning space theme. Expert-Verified Answer This planet had the Great Dark Spot - Neptune. reports: The planet in question is called Quaoar and it's the seventh largest of the known dwarf planets of which Pluto is the king. A mini-planet orbiting in the frigid outer reaches of the solar system has a Saturn-like ring of dust and debris that defies the rules of physics, a new study has revealed.
