March Moon at 2nd Perigee

   Our Moon reaches perigee, (closest to Earth), for the second time this orbit, on Tuesday March 30th. For this perigee the 18-day old waning gibbous Moon will be at a distance of 28.24 Earth diameters, 223,880 miles (360,300 km) from the Earth.

   On the date of the perigee Moon the 18-day old waning gibbous Moon will rise around 10 pm local time. The Moon is within the boundaries of Libra the Scales and on either side of the Moon are two stars with interesting sounding names. They are the stars Zubeneschamali and Zubenelgenubi. Despite these two stars belonging to the constellation Libra the Scales the translation of the star names mean “Northern Claw” (Zubeneschamali), and “Southern Claw” (Zubenelgenubi) of Scorpius the Scorpion.

   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*
