List of Solar System objects by surface gravity

Below is a list of Solar System objects by surface gravity.

Basis of calculations

The surface gravity at the equator of a body can in most cases be accurately calculated using Newton's law of universal gravitation and centrifugal force.

The "gravitational acceleration" at the equator is given by Newton's law of universal gravitation. The formula that follows from this law is::$a\_g\; =\; G\; frac\{m\}\{r^2\}$where:"a_g" is the magnitude of the gravitational acceleration:"G" is the gravitational constant:"m" is the mass of the celestial body:"r" is the equatorial radius of the celestial body (if this varies significantly, the mean equatorial radius is used)

The magnitude of the outward acceleration due to "centrifugal force" is given by:$a\_c\; =\; 4pi^2frac\{r\}\{T^2\}$where:"T" is the rotation period of the celestial body

The surface gravity at the equator is then given by:$g\; =\; a\_g\; -\; a\_c\; =\; frac\{G\; m\}\{r^2\}\; -\; frac\{4pi^2r\}\{T^2\}$

Data below this point are less reliable due to uncertainties in the figures for mass and radius, and irregularities in the shape and density of the objects listed.
