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.
