Kepler's laws of planetary motion are three scientific laws describing the motion of planets around the Sun.

• Kepler’s three laws of planetary motion can be stated as follows:

(1) All planets move about the Sun in elliptical orbits, having the Sun as one of the foci.

(2) A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.

(3) The squares of the sidereal periods (of revolution) of the planets are directly proportional to the cubes of their mean distances from the Sun.

They both are used to replace characters in a string

Nominal money relates more to it's measure of counting - so nominal figure of what is written on bill, while "real" relates more to it's purchasing power (usually between some periods of time). For instance 100 units in nominal could buy 2 units of good in 1950 and 1 unit of good in 2005, at the same time real value of this 100 nominal units are 100 real units in 1950 and 50 real units in 2005.

Same is with GDP. In nominal it can rise due to inflation while it can stay the same or even decrease in real value.
