Yottagram range[edit]
Following is a list of solar system objects more massive than 1021 kilograms (one yottagram [Yg]). Even the least massive of these objects is an approximate sphere.[1] Eris, a new trans-Neptunian object, is larger than Pluto but has an undetermined mass. An estimate is listed. See also List of planetary bodies.

- Leading asterisks (*) mark satellites.
- ^ Astronomical bodies form into rounded shapes (oblate spheroids) when the gravity of their own mass is sufficient to overcome the structural stength of their intrinsic materials and the friction between those materials. This is called gravitational collapse.
- ^ The mass of Eris is a very rough estimate based on a diameter of 2400 kilometers and a composition similar to that of the dwarf planet Pluto (density 2.03 g/cm³).
