Mass
In 2001, Michalak estimated Interamnia to have a mass of 6.9×1019 kg. Michalak's estimate depends on the masses of 19 Fortuna, 29 Amphitrite, and 16 Psyche; thus this mass was obtained assuming an incomplete dynamical model.
In 2007, Baer and Chesley estimated Interamnia to have a mass of (7.12±0.84)×1019 kg. As of 2010, Baer suggests Interamnia has a mass of only (3.90±0.18)×1019 kg. This makes it more massive than 511 Davida, though the error bars overlap.

Famous quotes containing the word mass:
“I am not a very sentimental man; and the best sentiment I can think of is, that if you collect the signatures of all persons who are no less distinguished than I, you will have a very undistinguishing mass of names.”
—Abraham Lincoln (1809–1865)
“The great mass of people judge well of things, for they are in natural ignorance, which is man’s true state.”
—Blaise Pascal (1623–1662)
“At first, he savored only the material quality of the sounds secreted by the instruments. And it had already been a great pleasure when, beneath the tiny line of the violin, slender, resistant, dense and driving, he noticed the mass of the piano’s part seeking to arise in a liquid splashing, polymorphous, undivided, level and clashing like the purple commotion of wave charmed and flattened by the moonlight.”
—Marcel Proust (1871–1922)
