August Moon at Apogee

   Our Moon reaches apogee, (furthest from Earth), for this orbit, on Sunday August 9th. At that time the last quarter Moon will be at a distance of 31.72 Earth diameters, 251,469 miles (404,700 km) from the Earth.

   On the date of the apogee the 19-day old waning gibbous Moon will be about 1o from the planet Mars and both very visible over the southern horizon in the hours before sunrise.

   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*
