Astronomers have identified a mysterious object orbiting far beyond Pluto that could qualify as a new dwarf planet in our solar system. The body takes roughly 280 years to complete one orbit around the sun, placing it in the distant outer solar system. The find adds to the growing list of candidate dwarf planets being examined beyond Neptune, and is drawing wide interest for what it may reveal about the solar system's outer reaches.
