Density is not measured directly but is calculated from measurements of temperature, pressure and humidity using the equation of state for air (a form of the ideal gas law). Atmospheric density decreases as the altitude increases. The radius of the inner core is about one-fifth of that of Earth. Density increases with depth, as described in the table on the right.
