March Moon at Perigee

3mar-perigee_moon   The Moon reaches perigee, (minimum distance from Earth), this month on Friday March 3rd. At that time the Moon will more or less be at a distance of 29.83 Earth diameters (369,062 km or 229,324 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 5.5-day old waxing crescent Moon is above the wstern horizon at sunset local time and sets a few hours later.
