Waxing Crescent Moon – Mars Conjunction

   Friday evening March 19th look for the 6.7-day old waxing crescent Moon to be about 3o from the ‘Red Planet’ Mars, and about 5-6o from the reddish star Aldebaran in Taurus the Bull. All three should just barely fit within the field of view of 7×50 binoculars.

A 3-for-1 Moon Event!

               Apogee – Descending Node – Conjunction with the Pleiades
   
Apogee Moon
   Our Moon reaches apogee, (furthest from Earth), for this orbit, on Thursday March 18th. For this apogee the 6.6-day old waxing crescent Moon will be at a distance of 31.77 Earth diameters, 251,841 miles (405,300 km) from the Earth.

Descending Node
   The 6.6-day old waxing crescent Moon crosses 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.

Conjunction with the Pleiades
   The apogee Moon, at nearly first quarter phase, will be above the western horizon and will be within a few degrees from the open star cluster the Pleiades. This should make for a good view with binoculars.


   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*

Moon – Uranus Conjunction

   Wednesday evening February 17th the 6-day old waxing crescent Moon will be about 3-4o from the outer and ringed Planet Uranus. While the Moon with an apparent magnitude of -11.5 will certainly be visible, Uranus with an apparent magnitude of 5.81 will not!

Crescent Moon – Neptune Conjunction

   Saturday February 13th the 2-day old thin waxing crescent Moon will be about 2-3o from the outer planet Neptune and about 6-7o to the west from Dwarf Planet Ceres. The Moon will pass by Ceres over the next 24 hours and by about this time tomorrow the Moon will be to the east from Ceres.
   I should point out that Ceres with an apparent magnitude between 8th and 9th and Neptune with an apparent magnitude between 7th and 8th neither will be visible to the unaided eye.
   However when you are looking toward the Moon you will be looking in the direction of these two distant members of our solar system. This graphic shows the position of the Earth, our Moon, Ceres, and Neptune on February 13th. From this perspective objects to the left of the Sun will be seen in the evening skies as the Earth rotates.

Waxing Crescent Moon – Mercury Conjunction

   Did you miss the 27-day old thin waning crescent Moon conjunction with Venus this past Monday morning? I did!
   Well there is an opportunity to see the thin crescent Moon on this side of new phase this Thursday evening January 14th. The 1.7-day young waxing crescent Moon will be over the western horizon in a line-up of sorts with Mercury, Jupiter, and Saturn all angled downward toward the western horizon. From Saturn to the Moon will span about 13o with Mercury, about 3-4o to the west, (down to the right) being the closest of the 3 planets.

   This animated graphic is set for 2-minute intervals starting at 5:30 pm CST.

Crescent Moon – Jupiter/Saturn Conjunctions


   As we are getting ready for the Grand Conjunction on the 21st the Moon reappears in the evening skies and waxes its way past Jupiter and Saturn on Wednesday the 16th and Thursday the 17th.


   The three set around 1-2 hours after local time for sunset, and all will fit within the field of view of 7×50 binoculars as the graphic is showing.

Waxing Crescent Moon Passes Jupiter and Saturn

   Wednesday and Thursday evenings November 18th and 19th at sunset local time look westward for our Moon and two planets. The 4-day old waxing crescent Moon will be about 6o to the west, right from Jupiter and about 9o from Saturn.

   During the 24-hours between the two evenings our Moon will have aged 1 day and will have moved approximately 15o toward the east. And by Friday the Moon will be about 5o to the east, left from Saturn and about 7o from Jupiter.

November Moon at Descending Node


   Tuesday November 17th the nearly 3-day old waxing crescent Moon crosses 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 date of the descending node the waxing crescent Moon will be over the southwestern horizon at sunset local time. Spread across the horizon from west to east are Jupiter, Saturn, Dwarf Planet Ceres, Neptune, and Mars.

October Moon at Descending Node

   Tuesday October 20th the 4-day old waxing crescent Moon crosses 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 date of the descending node the waxing crescent Moon will be over the southwestern horizon at sunset local time. Spread across the horizon from west to east are Jupiter, Saturn, Dwarf Planet Ceres, Neptune, and Mars.

Mercury- Spica & Moon – Antares

   Tuesday September 22nd shortly after sunset local time look toward the western horizon for the innermost planet Mercury to be about 1o from the bluish-white star Spica in Virgo the Harvest Maiden. The two should make for an interesting comparison in apparent magnitudes with Spica at 0.96 and Mercury with a -0.01 apparent magnitude.
   The nearly first quarter but still waxing crescent Moon will be about 7-8o from the reddish star Antares in Scorpius the Scorpion. Both are positioned over the southern horizon.
