In the beginning was chaos. Then along came Quaoar with a spring in his step and a song in his heart. He danced and whirled and sang the Song of Creation, and thus the Universe began.
It was simply the discovery that our solar system has yet another planet orbiting the Sun, confirming the existence of what Alan Stern describes as a third class of planets, the dwarf planets. Considering they are the authority on the subject, acknowledging their definition would seem like the sensible thing to do. Regardless of your feelings towards them, their rulings are pertinent to our reporting, and will be included. Quaoar is a dwarf planet because it is in hydrostatic equilibrium and orbits a star, regardless of whether or not the IAU recognizes it as such.
Brown did not lead them like one leads a donkey with a carrot. They are all listed as co-discoverers. This should end now. Skip to content. Like this: Like Loading Retrieved 27 February Minor Planet Electronic Circular.

It is almost certain that Quaoar is larger than all objects of the asteroid belt between Mars and Jupiter. It orbits the Sun in an almost perfect circular orbit at a distance of about 6. It takes Quaoar My general method is to take some aspect of the planetary symbol and apply it to symbols differentiating the moons, usually the initial of the moon's name in the appropriate writing system.
I offer these symbols up to the public domain, for use by future astronomers, future astrologers, and anyone else who's interested. Mars has two moons, Phobos and Deimos.
The symbols for them are based on the lower-case versions of the Greek letters Phi and Delta, which begin those two names in the original Greek, with the arrow from Mars's symbol added on. The Jovian gas giants each have a large number of moons at least 13 for Neptune, at least 63 for Jupiter. It's not really feasible to include them all, but some are larger than others. I've chosen an admittedly arbitrary threshold of 10 Zg 10 19 kg and created symbols for any moon larger than that, which lets in Saturn's moon Hyperion but not Jupiter's largest non-Galilean moon Amalthea.
This is also near the point at which moons become non-spherical - there are some non-spherical objects above this line, but no spherical ones below. Jupiter has four "large" moons - the four Galilean moons. For their symbols, the Greek letter beginning their names is combined with the cross at the bottom of the symbol for Jupiter.

These are two of the observations that were used to determine the mass of Quaoar from the size of Weywot's orbit. Most NASA images are in the public domain.
