October Moon at Apogee

31oct-apogee_moon
   Our Moon reaches apogee, (greatest distance from Earth), on Monday October 31st. At that time the Moon will more or less be at a distance of 31.88 Earth diameters (406,662 km or 252,688 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?”


   
   The just past new Moon, a 1.25-day old waxing crescent Moon, is close to the Sun and sets within an hour after sunset.
