August Perigee Moon

Our Moon reaches perigee, (closest distance to Earth), for this orbit on Friday August 18th. At that time the Moon will be at a distance of 28.70 Earth diameters (366,121 km or 227,497 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*

   On the day of the perigee Moon the 26-day old thin waning crescent Moon is above the eastern horizon about 30 minutes to an hour before the Sun rises. The inner planet Venus (-3.97 apparent magnitude) is within about 9o from the Moon while the Dwarf Planet Ceres, at an apparent 8th magnitude is too dim to be visible to the naked eye, is about 8o from the Moon.
