The Twins Point the Way

   Wednesday evening January 27th the nearly full Moon, a 14-day old waxing gibbous Moon, will be about 6-7o from the star Pollux, one of the two twin stars of Gemini the Twins. The other ‘twin star’, the other brother, is Castor.

   Off to the west over the southern horizon are the planet Mars and Uranus. Further west is Neptune, and the Dwarf Planets Eris and Ceres. Earlier in the evening, after sunset local time the innermost planet Mercury is over the western horizon.

The Twins Get Mooned!

   Wednesday morning December 30th watch for the full Moon to be in the grasp of the Gemini Twins. Hard to miss the full Moon, but just in case, it is over the western horizon near the ‘Twin Stars’ stars Pollux and Castor, on the right shoulder of Pollux.

Waning Gibbous Moon and the Twins

   Thursday evening December 3rd the 20-day old waning gibbous Moon will be in the arms of the Gemini Twins. Look for the Moon, Pollux and Castor as they rise a couple of hours after sunset local time.

Moon-Venus-M35 Conjunction

   Saturday morning August 15th the thin 25-day old waning crescent Moon will be about 2-3o from the inner planet Venus, and about 3-4o from the open star cluster M-35. All three are located near the feet of the Gemini Twins.
   The contrast in apparent magnitudes is very striking with the Moon shining at -10.7 compared to the -4.3 apparent magnitude of Venus. M-35, with an apparent magnitude of 5.3 will be difficult if not impossible to see with the bright Moon and Venus nearby. Under other conditions M-35 is visible to the naked-eye under dark skies. All three rise 2-3 hours before sunrise local time and will easily fit within the field of view of binoculars. To see just Venus and M-35 wait until tomorrow after the Moon has moved further east, is a thinner crescent and less bright. However Venus will have also moved a bit more than 1o east as it orbits along.
   If you can see the crescent Moon after sunrise it may even be possible to see Venus during the daytime using the Moon as a guide for where to look.

Venus Pass by M-35

Tuesday morning August 11th the inner planet Venus will be about 3-4o from the open star cluster M-35. Located near the feet of the Gemini Twins M-35 contains thousands of stars within an area about the size of the full Moon. M-35 is located around 5,000 light years distant.

   M-35 has an apparent magnitude of approximately 5.0 so it is possible to see M-35 with the naked eye and is certainly easily seen with binoculars. For the ‘record’ Venus has an apparent magnitude of -4.31, which by comparison is ‘way brighter’!!

Sun Not in Gemini

  According to the pseudoscience of astrology the Sun enters the constellation of the Gemini Twins on Wednesday May 20th. 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.

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.

December Moon at Ascending Node

   Friday December 13th the 17.5-day old waning gibbous Moon rises between the legs of the Gemini Twins. The Moon will be about 10-11o to the west from the ‘Twin’ Stars Pollux and Gemini. As it is rising the Moon will be crossing the plane of the ecliptic moving north. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is actually the Earth’s orbit and the Moon’s orbit is inclined about 6o from the ecliptic. So there are two node intersections, the ascending and descending nodes.

   Does our Moon actually go around the Earth as many graphics show? 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*

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.

Sun Does Not Enter Gemini

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.
