March Moon at Perigee

Whoops!! I did tis way too early!!! The Moon is actually at perigee Not apogee.
   Our Moon reaches perigee, (closest to Earth), for this orbit, on Monday March 1st. For this perigee the 18.25-day old waning gibbous Moon will be at a distance of 28.64 Earth diameters, 227,049 miles (365,400 km) from the Earth.

   On the date of the perigee Moon the waning gibbous Moon will rise around mid-evening local time. Interestingly, as it rises, the Moon will be part of the mnemonic: “Follow the arc to Arcturus and then speed to Spica.”


   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*

October Moon at Apogee

   Our Moon reaches apogee, (furthest from Earth), for this orbit, on Saturday October 3rd. For this apogee the 16-day old waning gibbous Moon will be at a distance of 31.85 Earth diameters, 252,463 miles (406,300 km) from the Earth.


   On the date of the apogee the 16-day old waning gibbous Moon will be about 1-2o to the east from the planet Mars and both very visible through the night hours, and shining brightly over the western horizon at sunrise.

   Our Moon and Mars should make for an interesting view with binoculars but considering the difference in apparent brightness (Moon: -12.6 vs Mars: -2.52) the Moon’s reflected sunlight will ‘drown out’ Mars. On the other hand, or direction, Venus is still close to the ‘heart of the Lion’ the star Regulus. Venus is unmistakable with an apparent magnitude -4.07 of compared to the 1.34 apparent magnitude of Regulus.
