July Moon at Apogee

   Our Moon reaches apogee, (greatest distance from Earth), on Thursday July 6th. At that time the Moon will more or less be at a distance of 31.82 Earth diameters (405,934 km or 252,235 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*

Read this very informative article about the Earth-Moon system and their orbital motions, written by Joe Hanson. “Do We Orbit the Moon?”

   On the day of the apogee Moon the 13-day old nearly full Moon, but still in the waxing gibbous phase, rises around local time for sunset and is about 2o from Saturn and around 14-15o degrees from the reddish star Antares in Scorpius the Scorpion.
