how is the orbit of the moon around the earth is different than the orbit of the earth around the sun

Hello Ariel,

The only difference between earth-sun and moon-earth orbits is a matter of scale.   The basic physics behind these phenomena are the same.  There is a  gravitational force between two objects proportional to both their masses and inversely proportional to the square of the distance between them.  The resulting orbits first calculated by Newton agreed with the observations of Kepler on the orbital periods of the planets around the sun.  See for more information.
