# 8.3.1 - The moons of Mars

 In order to be able to clearly create an e-function, 3 data points are required. But Mars only has 2 moons. Since both moons orbit Mars relatively close, the surface of Mars can be used as a third value. The entire situation is given in the following table.

 Name Radius Nr ln(Radius) Nr calculated Mars equator 3396 0 8,13035355 0 Phobos 9376 1 9,14590851 1,05 Deimos 23459 2 10,0630095 2

 When logarithmized and transferred to a diagram, a surprising simplification results. The logarithmic values ??are already so linear that further linearization is no longer necessary.

Abbildung 8.3.6 – Linearization

 As before, the e-function can be determined from this. The equation for the approximation line is: y = ln R = 0.9963·x + 10,407 The following applies to the orbits of the moon: R = 33096·e0.9663·x [Km]
