Virgo Spikes the Moon

   Our Moon, after traversing the boundaries of the constellation Leo the Lion, will then do a similiar crossing of the constellation Virgo the Harvest Maiden. Roughly midway across Virgo is the bright blue-white star Spica. From mythologies the star Spica represents a harvested bundle of grasses, maybe wheat or oats.
   On the evening of June 28th the Moon will be about 7o to the west from Spica, and the next evening, June 29th the Moon will about 9-10o to the east from Spica.

June Apogee Moon

   Our Moon reaches perigee, (closest to Earth), for this orbit, on Wednesday June 3rd. At that time the Moon will be at a distance of 28.56 Earth diameters, 226,406 miles (364,366 km) from the Earth.

   On the day of the perigee Moon the 13.3-day old waxing gibbous Moon rises a couple of hours before the Sun sets placing the Moon over the southeastern horizon around mid-evening.

   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*

Mars on the Move

   Friday morning January 17th, before sunrise, the last quarter Moon will be about 5-6o from the blue-white star Spica in Virgo the Harvest Maiden. However the celestial highlight coming up is further east or lower and closer to the eastern horizon where there are two reddish-colored objects of about the same apparent brightness or magnitude. One object is the planet Mars and the other is the star Antares in Scorpius the Scorpion.

Mars passing Antares – January 17-23 – 6 am CST

   Watch over the next several mornings and you will be able to determine which one is Mars and which is Antares as one of them moves past the other – as this animated graphic is showing. Also, relative to Mars and Antares the Moon is waning in phase as it zips past the two.

   There is an interesting connection between the star Antares and the planet Mars, based on their similar reddish color. There are times like this year when the two are close and part of the mythology surrounding the two suggests that the star was given its name so as to not confuse it with the planet Mars. The name Antares comes from the Greek word translated to ‘Rival of Mars’.

   Whenever that was historically Mars was probably known as one of the ‘wandering stars’ from the Greek word ‘planetai’. So with its reddish color, like blood, this ‘wandering star’ came to represent Mars, the ‘G-d of War’. Antares, on the other hand is a red supergiant star with a diameter estimated to be such that if it were at the center of our solar system Antares would fill the solar system out to around the main asteroid belt between Mars and Jupiter.

Mid-Winter Skies

   Tuesday evening December 24th around sunset or after the skies darken look toward the western horizon and you can’t miss noticing the bright celestial object – the inner planet Venus. Also, despite the fact that we are now two seasons away from our summer (Northern Hemisphere), over the western horizon are three stars making up the ‘Summer Triangle’. These three stars each belong to a seperate constellation but together they form an asterism,not a constellation, but a recognizable star shape.

   Wednesday morning December 25th look toward the eastern horizon for the ‘Red Planet’ (Mars) to be above the horizon and about 15o from the reddish star Antares in Scorpius the Scorpion. In this graphic Antares is just above the horizon.
Higher above Mars, toward the right or the west, is a the bluish star Spica in Virgo the Harvest Maiden. And higher still but toward the left is another reddish star. This is Arcturus in Bootes the Herdsman.

   As this year and decade come to a close I’d like to thank all my readers and the universe in general for allowing me an opportunity to share things celestial.
Have a happy and safe Holiday however you celebrate.
