The '''surface area''' of any celestial body is the total measure of the area of its surface. For an object in a hydrostatic-equilibrium or near-spherical shape, the surface area is a function of the equatorial and polar radii of the object. But some objects, like the [[Mars|Martian]] [[moon]]s [[Phobos]] and [[Deimos]], have highly irregular shapes, and their surface areas do not lend themselves to an accurate calculation.
Surface areas of [[solar system]] bodies are often given not only in traditional units of area but also as a fraction or multiple of the surface area of the [[earth]].
