However, Ceres (r = 470 km) is the smallest body for which detailed measurements are consistent with hydrostatic equilibrium, [8] whereas Iapetus (r = 735 km) is the largest icy body that has been found to not be in hydrostatic equilibrium. [9]

(Indeed, Neptune's moon Triton is a captured dwarf planet, and Ceres formed in the same region of the Solar System as the moons of Jupiter and Saturn.) Alan Stern calls planetary-mass moons " satellite planets ", one of three categories of planet, together with dwarf planets and classical planets. [ 27 ]
By far the largest object within the belt is the dwarf planet Ceres. The total mass of the asteroid belt is significantly less than Pluto's, and roughly twice that of Pluto's moon Charon. The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter ...
Subsequently, on September 5, 2012, it concluded its Vesta mission and commenced its journey to Ceres. [2] On December 1, 2014, Dawn captured images revealing an extended disc around Ceres. In January 2015, it compiled a series of images of Ceres into a stop-motion animation, depicting its rotation in low resolution.
Theia (/ ˈ θ iː ə /) is a hypothesized ancient planet in the early Solar System which, according to the giant-impact hypothesis, collided with the early Earth around 4.5 billion years ago, with some of the resulting ejected debris coalescing to form the Moon.
