November Moon at Descending Node


   Friday November 1st 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.

   On the day of the node crossing the 5.0-day old waxing crescent Moon will be over the southwestern horizon and will be about 3-4o to the west from the ringed planet Saturn. By Saturday evening, the 2nd, the Moon will have moved to the east of Saturn and will be about 8o from Saturn. Jupiter shines brightly further to the west. However with a more level horizon the two inner planets Mercury and Venus are visible. And with binoculars or telescope the Dwarf Planet Ceres could be seen about 3-4o from Jupiter.

Two Conjunctions this Evening

   Thursday evening October 31st look toward the western horizon but not for trick or treaters. Rather look for the two inner planets to be within about 2-3o from each other, and a bit further eastward for the Moon to be about 4-5o from Jupiter. Also the Dwarf Planet Ceres is within 3-4o from the crescent Moon. However Ceres is at 8th as compared with Jupiter at -2.0 and the crescent Moon at -11.0 apparent magnitudes. And before anyone asks Venus is at -3.9 and Mercury at 0.63 apparent magnitude.
   Each of the pairs will easily fit within the field of view of binoculars.

Crescent Moon Near Venus and Mercury

   Tuesday evening October 29th a very thin 2-day young waxing crescent Moon will be about 4-5o from the two inner planets Mercury and Venus. All three will easily fit within the field of view of binoculars – however be careful as they are not that far from the setting Sun.

   Over the next several days as the Moon waxes toward first quarter phase the Moon will pass by the Dwarf Planet Ceres and the outer planet Jupiter and then Saturn.

Moon Gets Clawed

   Tuesday evening October 2nd the 4-day old waxing crescent Moon will be in the claws of Scorpius the Scorpion, and about 6-7o from the heart of Scorpius, the reddish star Antares. The Moon will be about 8o from 8th magnitude Dwarf Planet Ceres, and about 11-12o from -2 magnitude Jupiter.

Moon Along the ecliptic

   As the Earth and Moon orbit the Sun together the Moon follows an orbital path that takes it along the plane of the ecliptic (Earth’s orbit), sometimes above, and sometimes below. At least twice each orbit or during during the calendar period for that orbit the Moon will cross the ecliptic either as an ascending node or a descending node.
   As this short video shows the Moon will follow a path along the ecliptic and as it does so it will pass some of the brighter stars and planets that are arranged on or near the ecliptic.
   You may also notice a steady shift of the sky toward the west. This is the effect of the Earth in motion, revolving, around the Sun. Since the Earth covers the 360o orbit in approximately 365 days the Earth moves almost 1o each day, and the sky in turn has the noticeable westward shift of the same amount.
