Waxing Crescent Moon Near the Pleiades


   Thursday evening February 22nd the 7-day old first quarter Moon will be 8-9o from the open star cluster the Pleiades, and about 7o from the open star cluster the Hyades. With my 10×50 binoculars the two star clusters are just out of the field of view, but become visible with a slight nudge of my head!

Go Fish!


   Monday evening January 22nd the 6-day old waxing crescent Moon will be in transit between two members of the ‘water-world’ part of our skies. The constellations Cetus the Whale and Pisces the Fishes will be the hosts for the Moon for the next few days. This animated graphic starts with Monday and is set to 1-day intervals ending on the 26th.

January Moon at Descending Moon


   Thursday January 18th the waxing crescent 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 2-day old thin waxing crescent Moon will be over the southwestern horizon an hour or so after sunset local time.

December Moon at Descending Node


   Friday December 22nd the waxing crescent 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 4.75-day old waxing crescent Moon will be over the southwestern horizon an hour or so after sunset local time.

December Moon at Apogee

   Our Moon reaches apogee, (greatest distance from Earth), on Tuesday December 19th. At that time the Moon will more or less be at a distance of 32.38 Earth diameters (406,603 km or 252,651 miles) from the Earth.

   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*

   On the day of the apogee the 1.7-day old very thin waxing crescent Moon will be over the southwestern horizon at around sunset local time. Not that it will be visible Dwarf Planet Pluto is a couple of degrees to the left from the Moon.

Waxing Crescent Moon Conjunctions with Mercury and Saturn

   Over the next two evenings, November 19th and 20th the waxing crescent Moon will be passing by the innermost planet Mercury and then one of the outer planets, Saturn. The thin 1.5-day old waxing crescent Moon will be near Mercury on Sunday the 19th, and then the 2.5-day old thin waxing crescent Moon will be near Saturn on Monday the 20th.
