Sun Not Really in Virgo

   According to the pseudoscience of astrology the Sun enters the constellation of Virgo the Maiden on Friday August 23rd. When in fact the actual position of the Sun is toward the west and still within the boundaries of the constellation of Leo the Lion.

   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.

August Moon at Descending Node


   Monday August 12th the Moon will be crossing the plane of the ecliptic moving south. This is known as the descending node, one of two intersections the Moon’s orbital path (dark green line) has with the ecliptic.

   On the day of the node crossing the 12.0-day old waxing gibbous Moon will be over the southern horizon and will be about 6-7o to the east from the ringed planet Saturn. Jupiter shines brightly further to the west near the reddish star Antares. With binoculars or telescope the dwarf planet Ceres may be visible.

August Moon at Perigee

   Our Moon reaches perigee, (closest distance to Earth), for this orbit, on Friday August 2nd. At that time the Moon will be at a distance of 28.175 Earth diameters, 223,319 miles (359,398 km) from the Earth.

   On the day of the perigee Moon the 2-day old thin waxing crescent Moon will be over the western horizon setting about 1 hour after the Sun sets.

   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*

July Moon at 2nd Ascending Node

   Tuesday July 30th the 27.5-day old thin waning crescent Moon will be crossing the plane of the ecliptic moving north relative to the ecliptic. 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.

   On the day of the node crossing the very thin waning crescent Moon rises about an hour before the Sun rises and is located nearly directly west from the ‘Twin’ stars, Pollux and Castor.

Correction to Post

   Okay, I screwed up and sent out a very incorrect post a few minutes ago.
Here is a link to the corrected post.
Sun Not in Leo

Sun Not in Leo


   According to the pseudoscience of astrology, Tuesday July 23rd the sun will be entering the constellation of Leo the Lion. In fact the Sun is still within the boundaries of the constellation Cancer the Crab, having just entered that region two days ago.
   The difference between the two locations of the Sun, the correct astronomical vs. the incorrect astrological, is due to the effects of precession, or more specifically, the precession of the Earth’s axis. The Earth wobbles on its axis like a spinning top does as the top slows down. So, in approximately 26,000 years the Earth will have spun, or wobbled one time. This is a repetitive cycle and over the course of one precession cycle the poles of the Earth trace out a circle against the background stars over their respective pole. any star on or nearest to this precession circle is the pole star. Currently the north pole of the Earth points toward Polaris and within this century, due to precession, will point the closest it will be, and then over time the Earth’s north pole will shift away.
   Another effect of precession has been to cause the celestial grid system to shift moving the original signs of the zodiac by at least one constellation to the west. In other words the Sun is more to the east which in effect means that whatever your zodiacal sign may be according to astrology, you are really the constellation to the west, or before it according to Astronomy.
   Click here to read a little more about precession from a previous blog.
   The Science of Astronomy has its roots in astrology with the origins of astrology beginning several millennia ago possibly by the Babylonians. Regardless of its origins the basis for at least Sun astrology, the popularized version printed in newspapers, is the position of the Sun relative to stars in the background. However we now know that due to the effects of precession the Sun’s position is no longer as it was during the beginnings of astrology.
    The slideshow below shows the sun’s position within Cancer on July 22nd 2016 AD, and then shifts to show the sun in Leo 4,000 years ago on 22 July 2016 BC. Precession has shifted the sun’s position one constellation to the west.

Sun Enters Cancer – 2019

19july-view-from-earth   Sunday July 21st the Sun in its apparent eastward motion along the ecliptic, moves out of the constellation Gemini the Twins and into the constellation of Cancer the Crab. 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.
