Astronomers have made a strange discovery near the edge of the solar system. They have discovered rings around a dwarf planet named Qua'uar. Here's why scientists are stunned. A planet's rings reside within its rosh limit, in the distance within which its gravitational forces rip apart moons and other celestial bodies. Rings outside this limit gradually merge to create moons within a few decades. But in the case of Qua'uar, its rings orbit it at a distance of 4,100 km or about 2,550 miles from its center. That's about four times its diameter and significantly further than Qua'uar's rosh limit. So, this discovery has challenged our notion that rings can only exist inside the rosh limit. This shows there's a lot to be discovered within the solar system, and some discoveries could change our understanding of the laws of physics.
