July Perigee Moon

jul5-perigee-moon   The Moon reaches perigee, (minimum distance from Earth), this month on Sunday July 5th at 18:55 UT (1:35 pm CDT). At that time the Moon will more or less be at a distance of 28.78 Earth diameters (367,093 km or 228,101 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*

   The waning gibbous Moon rises around midnight local time and is over the southern horizon at sunrise. As this graphic shows the right side of the asterism “the Square of Pegasus” is lined up with the Moon.
