The listed objects currently include most objects in the asteroid belt and moons of the giant planets in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following reference. [58] Asteroid spectral types are mostly Tholen, but some might be SMASS.

The smallest natural satellite that is gravitationally rounded is Saturn I Mimas (radius 198.2 ± 0.4 km). This is smaller than the largest natural satellite that is known not to be gravitationally rounded, Neptune VIII Proteus (radius 210 ± 7 km ).

The trans-Neptunian objects in the following tables, except Salacia, are agreed by Brown, Tancredi et al., Grundy et al., and Emery et al. to be probable dwarf planets, or close to it. Salacia has been included as the largest TNO not generally agreed to be a dwarf planet; it is a borderline body by many criteria, and is therefore italicized.
The largest asteroids with an accurately measured mass, because they have been studied by the probe Dawn, are 1 Ceres with a mass of (939.3 ± 0.5) × 10 18 kg, and 4 Vesta at (259.076 ± 0.001) × 10 18 kg. The third-largest asteroid with an accurately measured mass, because it has moons, is 87 Sylvia at (14.76 ± 0.06) × 10 18 kg.
The smallest known near-Earth asteroid is 2015 FF 415 with an absolute magnitude of 34.34, [116] corresponding to an estimated diameter of about 0.5 m (1.6 ft). [139] The largest such object is 1036 Ganymed, [116] with an absolute magnitude of 9.18 and directly measured irregular dimensions which are equivalent to a diameter of about 38 km (24 mi).
