A Table of Known Masses for Numerous Objects in the Solar System, in Kilograms, Solar Masses, Jovian Masses, Terran Masses, and Lunar Masses

solar system object masses

The source of the information in the first two columns is this Wikipedia page. I calculated the numbers in the other columns, so any errors there are my own.

There are many other objects of known mass in the solar system, but I tried not to skip any, as I worked from larger-mass objects down toward those of smaller mass. Skipping some was necessary, though, for there are many objects (the likely dwarf planet Sedna is but one example) for which the mass is simply unknown. The next one I encountered after the asteroid Pallas did not have a name, but merely an alphanumerical designation, so I decided to stop there.

  1. Why do you give the weights in kilograms? Everyone else use metres, or as GM, in m³/s², so

    Sun = 1476.6255 metres Earth = 4.4350289 mm.

    Earth = 3.9860012E14 cu metres / sec².

    That’s what they poke satalites around space with.

    • Kilograms measure mass, and those other units don’t. I was giving masses, not weights, primarily because mass is what matters (no pun intended) when calculating gravitational forces between these objects. A similar table, of course, could be made based on diameter, gravitational field strength at the surface, average distance from the sun, or any number of other things.
