Sun Enters Gemini

click on graphic to see it full size   Saturday June 22nd the Sun in its apparent eastward motion along the ecliptic, moves out of the constellation Taurus the Bull and into the constellation of The Gemini Twins. 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.

Sun Does Not Enter Gemini

  According to the pseudoscience of astrology the Sun enters the constellation of the Gemini Twins on Tuesday May 21st. When in fact the actual position of the Sun on this date is still within the boundary of the constellation of Taurus the Bull, as this graphic and the banner graphic show.

November Moon at Perigee

   Our Moon reaches perigee, (closest distance to Earth), for this orbit on Monday November 26th. At that time the Moon will be at a distance of 28.74 Earth diameters 227,809 miles (366,623 km) from the Earth.

   The 18-day old Waning gibbous rises after sunset and is visible all night between the Gemini Twin stars and the bright star Capella in Canis Minor. Off to the east is the inner planet Venus shining brightly with an apparent magnitude of -4.6, and within about 4o from the blue-white star Spica (0.9 apparent magnitude) in Virgo the Harvest Maiden. About 10o east from Venus is the closest Dwarf Planet, Ceres. With an apparent magnitude of 8.0 Ceres is not visible to the unaided eye.

   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*

Venus and the Twins


   Over the next few evenings, June 7th to 10th, the inner planet Venus will pass the star Pollux, marking the head of one of the Gemini Twins. Pollux is on the left side as we view the ‘Twins’ face-on. This animated graphic is set for 10 pm CDT and shows the daily movement of Venus toward the east, combined with the daily motion of the stars toward the west as the Earth revolves around the Sun.


   The separation between Venus and Pollux will vary from about 4.5o to about 5.5o allowing at least these two to fit within a binocular field of view.

Sun Not Really in Gemini

  According to the pseudoscience of astrology the Sun enters the constellation of the Gemini Twins on Monday May 21st. When in fact the actual position of the Sun on this date is still within the boundary of the constellation of Taurus the Bull, as this graphic and the banner graphic show.

Venus Gets Buzzed!

   Tuesday morning August 1st the inner planet Venus will pass within 3o from the open star cluster, M-35. Also known as the ‘Beehive Cluster’ this is an open star cluster located near the feet of the Gemini Twins. M-35 consists of several hundred stars and is approximately 2800 light years from our solar system. The star cluster has an apparent magnitude of around 5.5 making it naked-eye visible and certainly a binocular-worthy object.

   Through binoculars it is easy to see M-35 as well as a 3rd and a 2nd magnitude star within a couple of degrees. However the ‘ruler’ of the binocular field of view is Venus with a -4.0 magnitude.

Moon Near a Beehive


   Very early Sunday morning October 23rd the 22-day old last quarter Moon will be a few degrees from the open star cluster M-44, or commonly known as the ‘Beehive Cluster‘. This should make for an interesting sight with binoculars despite the reflected light from the Moon.

   If you are not a late night observer but like me an early morning observer then the Moon will still be close to M-44 before sunrise. However at that time look south-southeast and high above the horizon. To the right is Procyon in Canis Minor and above the Moon are the ‘Twins’ Pollux and Castor.
