^ The planetary discriminant for the planets is taken from material published by Stephen Soter.[52] Planetary discriminants for Ceres, Pluto and Eris taken from Soter, 2006. Planetary discriminants of all other bodies calculated from the Kuiper belt mass estimate given by Lorenzo Iorio.[53]
^ Saturn satellite info taken from NASA Saturnian Satellite Fact Sheet.[54]
^ With the exception of the Sun and Earth symbols, astronomical symbols are mostly used by astrologers today; although occasional use of the other planet symbols (and Pluto) in astronomical contexts still exists,[55] it is officially discouraged.[56]
Astronomical symbols for the Sun, the planets (first symbol for Uranus), and the Moon, as well as the first symbol for Pluto were taken from NASA Solar System Exploration.[57] The other symbols are even rarer in modern astronomy.
The symbol for Ceres was taken from material published by James L. Hilton; it was used astronomically when Ceres was thought to be a major planet, and continues to be used today in astrology.[58]
The second symbol for Uranus was also taken from there; it is more common in astrology than the first symbol.[58]
The symbols for Haumea, Makemake, and Eris appear in a NASA JPL infographic, as does the second symbol for Pluto; they are otherwise mostly astrological symbols.[59]
The symbols for Quaoar, Sedna, Orcus, and Gonggong were taken from the astrology progam Astrolog; so far they have only been used in astrology.[60]
The Moon is the only natural satellite with a standard symbol. Symbols have been proposed for the other natural satellites on this list, but have yet to receive widespread adoption amongst astronomers or astrologers.
The missing dwarf-planet symbols for Haumea, Makemake, Gonggong, Quaoar and Orcus have been preliminarily accepted for Unicode 16 at code points U+1F77B to 1F77F.[61]

^ Radii for plutoid candidates taken from material published by John A. Stansberry[63]
^ Axial tilts for most satellites assumed to be zero in accordance with the Explanatory Supplement to the Astronomical Almanac: "In the absence of other information, the axis of rotation is assumed to be normal to the mean orbital plane."[64]

^ Calculated using the formula where Teff = 54.8 K at 52 AU, is the geometric albedo, q = 0.8 is the phase integral, and is the distance from the Sun in AU. This formula is a simplified version of that in section 2.2 of Stansberry, 2007,[63] where emissivity and beaming parameter were assumed equal unity, and was replaced with 4 accounting for the difference between circle and sphere. All parameters mentioned above were taken from the same paper.
^ Surface area was calculated using the formula for a scalene ellipsoid:
where is the modular angle, or angular eccentricity; and , are the incomplete elliptic integrals of the first and second kind, respectively. The values 980 km, 759 km, and 498 km were used for a, b, and c respectively.
^ The ratio between the mass of the object and those in its immediate neighborhood. Used to distinguish between a planet and a dwarf planet.
^ This object's rotation is synchronous with its orbital period, meaning that it only ever shows one face to its primary.
^ Objects' planetary discriminants based on their similar orbits to Eris. Sedna's population is currently too little-known for a planetary discriminant to be determined.
^ "Unless otherwise cited" means that the information contained in the citation is applicable to an entire line or column of a chart, unless another citation specifically notes otherwise. For example, Titan's mean surface temperature is cited to the reference in its cell; it is not calculated like the temperatures of most of the other satellites here, because it has an atmosphere that makes the formula inapplicable.
