Moon – Regulus Conjunction

   Wednesday morning November 20th watch for the 3rd quarter Moon to be about 5-6o to the east from the heart of Leo the Lion, the star Regulus. This graphic shows the skies at 1:00 am CST – my time zone, and is great for those up late or cannot sleep!
   However a more reasonable time for seeing this conjunction may be a few hours later as the Sun rises.

Heads Toward the Moon

   Early Monday morning October 21st the last Quarter Moon will be high over the southeastern horizon and more or less lined up with the ‘Twin Stars’ of Gemini, Pollux and Castor. The Moon will be about 4-5o from Pollux and about 9-10o from Castor.

Moon at Apogee

   Our Moon reaches apogee, (greatest distance from Earth), for this orbit, on Sunday May 26th. At that time the Moon will be at a distance of 31.68 Earth diameters 251,117 miles (404,134 km) from the Earth.

   The 22-day old last quarter Moon rises after midnight local time and sets later that same day.

   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*

April Apogee Moon

April Apogee Moon   Our Moon reaches apogee, (greatest distance from Earth), on Monday April 8 th. At that time the Moon will more or less be at a distance of 31.68 Earth diameters (404,144 km or 251,123 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 22-day old last quarter Moon will be over the eastern horizon at around sunrise local time and within about 11o from the ringed planet Saturn, and about 8-o from Mars.

Dance of the Planets Continues

   In a previous post I described how the two inner planets, Mercury and Venus, and an outer planet, Mars, will be visible over the eastern horizon in the hour or so before the Sun rises. Given their respective orbital speeds the three planets will interact with one another in a series of conjunctions that at times will include the star Regulus in Leo the Lion.
   Once again facing east along 50 Highway at around 6 am CDT with early morning traffic just starting to increase. Still dealing with haze and low clouds, some of which are remnants of Hurricane Irma.

Triangulating with the Moon

   Tuesday morning, August 15th the 23-day old first quarter Moon will be the point of a celestial triangle with the two open star clusters, the Pleiades, and the Hyades as this graphic shows. The v-shaped Hyades forms the face of Taurus the Bull while the ‘dipper-shaped’ Pleiades lies along the Bull’s shoulder. Both open star clusters are about 8o from the Moon.
