This page lists the largest named objects in the Solar System, ranked by mass,
accompanied by official or unofficial symbols.
It only includes those objects that have a mass of at least 10^{19} kg
(10 Zg) and that have been given permanent names.
For the planets and sun I show their traditional symbols.
The moons of other
planets and large trans-Neptunian objects are
accompanied by the symbols I've created for them.
The asteroid symbols are from diverse sources -
see that page for details.
Uranus, Pluto, Pallas, and Vesta have multiple widely accepted symbols - in
each case, I've chosen one based on my own aesthetic preferences.
Mass data is from
Wikipedia.
