|A little-known outer member of the Solar System, orbiting the Sun beyond the orbit of Neptune. Chaos has a dark, non-reflective surface with a low albedo value of just 5%. It is estimated to be some 600 km in diameter, though within a sigificant margin of error.
One of the objects described as cubewano, a cloud of planetoids circling the Solar System beyond the orbit of Neptune in the region known as the Kuiper Belt. Chaos takes its name from Greek mythology, where it signified the void from which the first gods emerged.
Chaos pursues a rather eccentric orbit, at distance from the Sun varying between about forty and fifty AU (an orbital distance approximately comparable with that of Pluto, though unlike Chaos, Pluto's more eccentric orbital path brings it at times within that of Neptune).
Though its nature is not well known, Chaos' diameter can be estimated at some 600 km. This makes Chaos rather small for a potential dwarf planet: in fact it is only about half the diameter of Pluto's moon Charon.
