Ceres has a mass of as determined from the "Dawn" spacecraft. With this mass Ceres composes approximately a third of the estimated total 3.0 ± 0.2 kg mass of the asteroid belt, or 1.3% of the mass of the Moon. Ceres is close to being in hydrostatic equilibrium, and thus to being a dwarf planet. However, there are some deviations from an equilibrium shape that have yet to be fully explained. Among Solar System bodies, Ceres is intermediate in size between the smaller asteroid Vesta and the larger moon Tethys, and approximately the size of the large trans-Neptunian object . Its surface area is approximately the same as the land area of India or Argentina. In July 2018, NASA released a comparison of physical features found on Ceres with similar ones present on Earth.
