  As seen from Earth, both Mercury and Venus have phases like our moon.
 That's because they circle the sun inside Earth's orbit.
 Planets that orbit between Earth and the sun are known as inner or inferior planets.
     The phases of Venus were first observed by Galileo Galilei in the early 1600s.
