May Perigee Moon

may15-perigee   The Moon reaches perigee, (minimum distance from Earth), this month on Friday May 15th at 00:26 UT (7:26 pm CDT Thursday May 14th). At that time the Moon will more or less be at a distance of 28.70 Earth diameters (366,024 km or 227,437 miles) from the Earth.
   Does our Moon actually go around the Earth as this graphic shows? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*
