October Moon at Apogee and at Descending Node

   Wednesday October 17th the 9-day old waxing gibbous Moon will be crossing 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.
   Also on the same day the waxing gibbous Moon reaches apogee, (greatest distance from Earth), on Wednesday October 17th. At that time the Moon will more or less be at a distance of 31.69 Earth diameters, (251,175 miles (404,227 km), from the Earth.

A Busy Moon: Apogee; Descending Node; Mars Conjunction

   Thursday September 20th the waxing gibbous 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.

   Our Moon also reaches apogee, (greatest distance from Earth), on Thursday September 20th. At that time the Moon will more or less be at a distance of 31.74 Earth diameters (361,354 km or 224,535 miles) from the Earth.

   On the evening of the apogee and node crossing the 11-day old waxing gibbous Moon will be over the southeast horizon at sunset in conjunction with the ‘Red Planet’, passing within 10-11o east from the planet Mars. Joining the Moon and Mars are the planets Saturn, Jupiter, and Venus – all to the west from the Moon and Mars.
