Moon – Jupiter Conjunction

   Wednesday morning March 27th the 20-day old waning gibbous Moon will be within about 4o from the outer giant ringed planet Jupiter. The Moon and Jupiter are both within about 20o east (left) from the reddish star Antares in Scorpius the Scorpion.
   Further eastward is another outer ringed giant planet, Saturn. This is where the Moon will be in 2 days.

Venus and Jupiter in Motion

   If the morning skies are clear and the temperature is tolerable go out before sunrise local time and look toward the east. The two brightest stellar objects are the planets Venus (brightest) and Jupiter. A few degrees from Jupiter is the reddish star Antares in Scorpius the Scorpion. Dwarf Planet Ceres is also in this part of the sky but it is too dim to be seen with the unaided eye. As the graphic shows this is also near the Milky Way but seeing that would require much darker skies than many of us live under.

   Both planets are in motion as they orbit the Sun following their respective orbital path. As an inner planet and much closer to the Sun Venus moves more quickly than Jupiter so as days pass Venus will noticeable move more so than Jupiter. Venus was at its western elongation last month and now Venus is in the part of its orbit where it is moving eastward toward the Sun. As Venus moves in that direction Venus will catch up to and then pass Jupiter, coming the closest on January 23rd.
   The animated graphic is set for 1-day intervals from January 15th to January 31st.
   For comparison Venus moves 1.6o each day while Jupiter moves 0.083o each day. The Earth is also in motion and moves about 1.0o each day. So as the Earth moves the sky appears to move toward the west and as this happens Saturn comes into view toward the end of January. The waning crescent Moon shows up also at the end of the month.

Sun Enters Scorpius

   Friday November 23rd the Sun, in its apparent eastward motion along the ecliptic, moves out of the constellation Libra the Scales and into the constellation of Scorpius the Scorpion. This is the true or actual position of the Sun as opposed to the pseudoscience of astrology which usually has the astrological Sun one constellation ahead or east from the Astronomical Sun’s position.

   Read a little more about how astrology has the Sun incorrectly placed in a previous blog, and in another blog discussing the effects of precession.

Our Moon in Motion

Moon in Motion November 7-18

   During the evening hours between Wednesday November 7th – 18th the Moon will orbit eastward passing several planets and bright stars as it goes from a thin waxing crescent shape to just past first quarter and the waxing gibbous shape by the 18th.
    (The animated graphic is set to 1-day intervals.)
    In addition to the Moon moving along in its orbit the Earth is also moving eastward along its orbit around the Sun. As the Earth revolves the sky shifts toward the west gradually moving the stars closer to the western horizon. Even the planets gradually shift toward the western horizon and out of sight.

Sun Not in Scorpius

  According to the pseudoscience of astrology the Sun enters the constellation of Scorpio the Scorpion on Tuesday October 23nd. When in fact the actual position of the Sun is still within the boundaries of the constellation of Virgo the Harvest Maiden.
