August Perigee Moon

aug2-perigee-moon   The Moon reaches perigee, (minimum distance from Earth), this month on Sunday August 2nd at 10:08 UT (5:08 am CDT). At that time the Moon will more or less be at a distance of 28.39 Earth diameters (362,139 km or 225,027 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 18-day old waning gibbous Moon rises around 11 pm local time and is over the southern horizon at sunrise. As this graphic shows the Moon is more or less where it was at this time and Moon phase last month below the right side of the asterism “the Square of Pegasus” and nearly in line with that side.
