Motion in the presence of of gravity, in everyday life, conserves total energy, but can swap one form for another--as in a roller coaster, which speeds up at the low points and slows down at high ones. There are likely billions of comets orbiting our Sun in the Kuiper Belt and even more distant Oort Cloud. Furthermore, Venus appears smallest when it is in full phase and thus is farthest from Earth.
