Pluto has a neighbor! Ringed dwarf planet at the edge of our solar system defies laws of physics
If you think the controversy over calling Pluto a planet is the only thing happening at the edge of our solar system, think again! Researchers say there’s a unique dwarf planet with rings which defy the laws of physics sitting at the outer reaches of the solar system. Astronomers say the rings encircling a mysterious world named Quaoar are more than twice as far out as the rings of Saturn, Jupiter, Neptune, and Uranus.
The discovery is forcing scientists to rethink the origins of these structures. Astronomers discovered this dwarf planet after it passed in front of a background star as it orbited the Sun. The event lasting less than a minute was preceded and followed by two dips in light — indicative of a ring system. Read More…
