Named Objects in the Solar System by Mass

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 1019 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.
