List of solar system objects by mass

From Academic Kids

This is a list of solar system objects by mass, in decreasing order. This list is incomplete because the masses of many asteroids are not accurately known.

The ordering is not the same as the order of a list of solar system objects by radius because some objects are denser than others. For instance Neptune is more massive than Uranus despite being smaller, and Mercury is much more massive than Ganymede and Titan despite being smaller.

Many of these values were taken directly from the appropriate Wikipedia article. Some were taken from the Planetary Fact Sheets (http://nssdc.gsfc.nasa.gov/planetary/planetfact.html). The mass of 20000 Varuna was estimated based on values given at [1] (http://www.ifa.hawaii.edu/faculty/jewitt/varuna.html) for its diameter and density. Several large objects (90377 Sedna, 28978 Ixion, 50000 Quaoar, and 90482 Orcus) are not listed because they are not well-studied.
