   Today at 2 pm CDT (17 UT) the planet Venus will have reached what is described as its ‘theoretical dichotomy‘. From our perspective on Earth Venus will appear to be 50% illuminated as the banner graphic at the top of the page shows. Our Moon is on the west side of the Sun, and in its waning gibbous phases, so the Moon, for a couple of days, will resemble the phase appearance of Venus. Tomorrow, the 24th of March the last quarter Moon will most resemble the last-quarter appearing Venus.
   This animated graphic shows how the Earth, Sun, and Venus are arranged just one day after Venus had reached its greatest western elongation. It starts with an ecliptic perspective view of the Earth, Sun, and Venus from which you can see that Venus currently is north of the plane of the ecliptic. As the view switches to an overhead view you can see that the Earth, Sun, and Venus are more or less at at a right angle arrangement following yesterday’s greatest western elongation for Venus.
