As I said, that would only be true in a universe where the interplanetary 
medium would be an absolute vacuum, and where there were no friction.  In 
this universe, however, friction causes kinetic energy to be transformed 
into other, less directed forms of energy.

However, the fact that the motion of the planets of the Sol System (in 
particular, the rotation speed of Terra) is slowing due to internal friction 
and friction with the interplanetary medium (as for Terra’s rotation: mostly 
due to tidal effects) is rendered insignificant by the fact that Sol is 
projected to become a red giant before this decrease becomes significant.
