The planetary discriminant for the planets is taken from material published by Stephen Soter. 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.

| item2_value = 16 | 2 = Saturn satellite info taken from NASA Saturnian Satellite Fact Sheet.

| item3_value = 17 | 3 = 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, it is officially discouraged. 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.

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.

| item4_value = 18 | 4 = Uranus satellite info taken from NASA Uranian Satellite Fact Sheet.

| item5_value = 19 | 5 = Radii for plutoid candidates taken from material published by John A. Stansberry

| item7_value = 22 | 7 = Số lượng vệ tinh tự nhiên lấy từ tài liệu do Scott S. Sheppard công bố.

Manual calculations (unless otherwise cited)

Surface area A derived from the radius using A=4\pi r^2 , assuming sphericity.
| item2_value = 2 | 2 = Volume V derived from the radius using V=\frac{4}{3}\pi r^3 , assuming sphericity.
| item3_value = 3 | 3 = Density derived from the mass divided by the volume.
| item4_value = 4 | 4 = Surface gravity derived from the mass m, the gravitational constant G and the radius r: Gm/r2.
| item5_value = 5 | 5 = Escape velocity derived from the mass m, the gravitational constant G and the radius r: .
| item6_value = 14 | 6 = Orbital speed is calculated using the mean orbital radius and the orbital period, assuming a circular orbit.
| item7_value = 20 | 7 = Assuming a density of 2.0
| item8_value = 23 | 8 = Calculated using the formula T\ =\ \frac{T_{\textrm{eff}}(1-qp_\nu)^{1/4}}{\sqrt 2} \sqrt{52/r}, where Teff =&nbsp;54.8&nbsp;K at 52&nbsp;AU, p_\nu is the geometric albedo, q&nbsp;=&nbsp;0.8 is the phase integral, and r is the distance from the Sun in AU. This formula is a simplified version of that in section 2.2 of Stansberry, 2007,
