Objects being described by their relative size are often described as being comparatively big and little, or large and small, although "big and little tend to carry affective and evaluative connotations, whereas large and small tend to refer only to the size of a thing". [5]
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.
This book is done entirely in silhouette, exploring the different shapes of objects. The characters of two children, a boy and a girl are in dialogue about shapes. The two exchange their thoughts on how different shapes and objects are from each other. They exchange ideas of how big and small some objects are.
It is a small, irregularly shaped object with a mean radius of 11 km (7 mi). Its surface is very unreflective and dominated by impact craters. [D 7] [125] In particular, Phobos's surface has a very large Stickney impact crater that is roughly 4.5 km (2.8 mi) in radius. [126] Deimos is Mars's outer moon. Like Phobos, it is irregularly shaped ...
A dwarf planet is a small planetary-mass object that is in direct orbit around the Sun, massive enough to be gravitationally rounded, but insufficient to achieve orbital dominance like the eight classical planets of the Solar System.

1.280 Mm – diameter of the trans-Neptunian object 50000 Quaoar; 1.436 Mm – diameter of Iapetus, one of Saturn's major moons; 1.578 Mm – diameter of Titania, the largest of Uranus's moons; 1.960 Mm – estimated longest axis of Haumea; 2.326 Mm – diameter of the dwarf planet Eris, the largest trans-Neptunian object found to date
Characteristically, big (bright) objects are typically on inclined orbits, whereas the invariable plane regroups mostly small and dim objects. [21] It is difficult to estimate the diameter of TNOs. For very large objects, with very well known orbital elements (like Pluto), diameters can be precisely measured by occultation of stars.
