October Moon at Perigee

   Our Moon reaches perigee, (closest distance to Earth), for this orbit on Friday October 5th. At that time the Moon will be at a distance of 28.72 Earth diameters (227,668 miles (366,396 km) from the Earth.

   Friday morning October 5th the very thin 25-day old waning crescent Moon will be about 4-5o from the star Regulus in Leo the Lion.

   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 Ascending Node

   Thursday October 4th the waning crescent 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 the day of the node crossing the 26-day old thin waning crescent Moon will be about 1o from the open star cluster known as the ‘Beehive Cluster’, M-44. Given that the Moon has an apparent magnitude of 14.0 compared with the 4th magnitude of the Beehive Cluster it may be difficult to see the star cluster.

   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*

Moon Meets the Twins


   Wednesday morning October 3rd the 23-day old waning crescent Moon will be a few degrees from Pollux and Castor, the two stars making up the head of each of the Gemini Twins.

Scorpius Claws the Moon!

   Friday evening September 14th the 5-day old waxing Crescent Moon will be within about 8-9o from the reddish star Antares in Scorpius the Scorpion. Joining the Moon to the west is the planet Jupiter, and to the east the planets Saturn and Mars. The inner planet Venus has already set by the time this graphic is set for.

Moon in Conjunction with Jupiter


   Thursday evening September 13th the 4.5-day old waxing crescent Moon will be 4-5o from the outer planet Jupiter. Joining the Moon and Jupiter are the planets Venus, Saturn, and Mars.
   Jupiter, the Moon, and Zubenelgenubi, a star in Libra the Scales, will all easily fit within the field of view of binoculars.

Crescent Moon and the Planets

   Tuesday evening September 11th the 2.5-day old waxing crescent Moon will be 7-8o from the blue-white star Spica in Virgo the Harvest Maiden, and about 8-9o from the inner planet Venus. Joining Venus and the Moon are several planets arranged from west to east – Jupiter, Saturn, and Mars. Northwest from Venus is the dwarf planet Ceres, but at 8th apparent magnitude Ceres requires an optical aid like powerful binoculars or a telescope.to be seen.
