April Moon at Apogee

   Our Moon reaches apogee, (greatest distance from Earth), on Monday April 1st. At that time the Moon will more or less be at a distance of 31.79 Earth diameters 252,520 miles (406,391 km) from the Earth.

   Does our Moon actually go around the Earth? 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 apogee the 26-day old very thin waning crescent Moon will be over the southeastern horizon 30-60 minutes before sunrise local time.

March Moon at Descending Node #2

   Friday March 29th the Moon will be crossing the plane of the ecliptic moving south. This is known as the descending node, one of two intersections the Moon’s orbital path (dark green line) has with the ecliptic.
29 March 6 am CDT   On the day of the node crossing the 23-day old waning crescent Moon will be over the southeast horizon rising about 1-2 hours before the Sun rises. Toward the west from the Moon will be the outer ringed-planet Jupiter, and a bit further west the dwarf planet Ceres. About 4o east from the Moon is the outer ringed-planet Saturn. Both of these will easily fit within the field of view of 7×50 binoculars.

Moon – Jupiter Conjunction

   Wednesday morning March 27th the 20-day old waning gibbous Moon will be within about 4o from the outer giant ringed planet Jupiter. The Moon and Jupiter are both within about 20o east (left) from the reddish star Antares in Scorpius the Scorpion.
   Further eastward is another outer ringed giant planet, Saturn. This is where the Moon will be in 2 days.

Moon – Ceres Conjunction

   Tuesday morning March 26th the 20-day old waning gibbous Moon will be about 4o from Dwarf Planet Ceres, and about 10o from the reddish star Antares in Scorpius the Scorpion. Further east from the Moon is the planet Jupiter and is near where the Moon will be tomorrow.

Waning Gibbous Moon Passes Spica

   Over the next 2 days, March 21st and 22nd, the waning gibbous Moon will be passing by the blue-white star Spica in the constellation Virgo the Harvest Maiden, coming within 6-7o on the 21st and 10-11o on the 22nd.
   From the mythology about Virgo she is often depicted with a bundle of grasses, like wheat, clutched in her left hand. The star Spica represents that bundle.

March Moon at Perigee

   Our Moon reaches perigee, (closest distance to Earth), for this orbit, on Tuesday March 19th. At that time the Moon will be at a distance of 28.17 Earth diameters (223,309 miles – 359,381 km) from the Earth.

   The 13-day old nearly full, waxing gibbous, Moon rises shortly after sunset local time is visible all night. Over the southwestern horizon, as the Moon is rising,is the planet Mars which sets around midnight.

   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*
