An artist illustration of the Quaoar system in front of a background of white stars. Central in the figure sits a brownish planet. This is Quaoar, a dwarf planet in the outer Solar System. At a distance of about five times its radius sits a ring. This ring is made up out of small grey pieces of debris. At twice the distance of the ring, to the left of Quaoar, sits its moon Weywot. Weywot looks about a sixth the size of Quaoar but has the same brownish colour. To the right of this system, we see a bright star. This star is bigger than the background stars and represents the distant Sun
