December Moon at Ascending Node

   Friday December 8th the waning gibbous Moon will be crossing the plane of the ecliptic moving north relative to the ecliptic. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is actually the Earth’s orbit and the Moon’s orbit is inclined about 6o from the ecliptic. So there are two node intersections, the ascending and descending nodes.


   On December 8th the 21-day old waning gibbous Moon will be within the boundaries of Leo the Lion and about 3o east from the ‘Heart’ of the Lion, the star Regulus.

   Does our Moon actually go around the Earth as many graphics show? 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*

December Moon at Perigee


   Our Moon reaches perigee, (closest distance from Earth), for this orbit on Monday November 4th. At that time the Moon will be at a distance of 28.025 Earth diameters (367,492 km or 222,135 miles) from the Earth. This is approximately 17 hours after full Moon making this full Moon the year’s Super Moon.

   On the day of the perigee Moon the 16.5-day old waning gibbous Moon is above the eastern horizon about 1 hour after sunset local time. The Moon is located just east of Orion’s club and Orion appears to be swinging his club as if it were a baseball bat toward the Moon – but missed. Strike One!!.

November Moon at Apogee

   Our Moon reaches apogee, (greatest distance from Earth), on Tuesday November 21st. At that time the Moon will more or less be at a distance of 31.84 Earth diameters (406,132 km or 252,359 miles) from the Earth.

   On the day of the apogee the 3.5-day old waxing crescent Moon will be over the southwestern horizon at sunset local time. Were it not so bright the glow of the Milky Way in the background might have been visible. Saturn is visible, but it is low above the horizon.

Moon Splits the Distance


   Wednesday morning November 15th the thin 27-day waning crescent Moon will be located more or less between the planet Mars and the bluish-white star Spica in Virgo the Harvest Maiden.

Moon Conjunction with Mars and Spica


   Tuesday morning November 14th the waning crescent Moon will be within a few degrees from the ‘Red Planet’ Mars and the bluish-white star Spica in Virgo the Harvest Maiden. Then as this animated graphic illustrates the waning crescent Moon will pass by Jupiter and then Venus over the next few days.

November Moon at Ascending Node

   Friday November 10th the last quarter Moon will be crossing the plane of the ecliptic moving north relative to the ecliptic. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is actually the Earth’s orbit and the Moon’s orbit is inclined about 6o from the ecliptic. So there are two node intersections, the ascending and descending nodes.


   On November 10th the 22-day old last quarter Moon will be within the boundaries of Cancer the Crab and about 2-3o from M-44 the Beehive open star Cluster, and about 6o from Dwarf Planet Ceres.

   The three are close enough for all to fit within the field of view of binoculars.

November Moon at Perigee


   Our Moon reaches perigee, (closest distance from Earth), for this orbit on Monday November 6th. At that time the Moon will be at a distance of 28.33 Earth diameters (361,438 km or 224,587 miles) from the Earth.

   On the day of the perigee Moon the 18-day old waning gibbous Moon is above the eastern horizon around 10:30 pm local time. The Moon is located just west of Orion’s club and Orion appears to be swinging his club as if it were a baseball bat toward the Moon.
