FOR VENUS AS AN EVENING STAR 2013, THIS CYCLE IS COMPLETED.
Venus has phases as seen through a telescope as
seen in the image above.
After a brilliant performance in the morning sky during the 2012, Venus appears as an Evening Star in the spring of 2013. On March 28, 2013, Venus passes superior conjunction on the far side of its orbit behind the sun.
Earth, Sun, and Venus are in a line with the sun in the middle, as shown in the chart above. Venus then reappears in the western evening sky. By April’s end Venus is setting about 45 minutes after the sun, appearing as a bright star near the western horizon as the sky darkens. The chart above shows the difference between the times of sunset and Venus setting from data from the U.S. Naval Observatory. (Click the graph to see it larger.) By the end of May, Venus sets nearly 80 minutes after the sun, making its way into a darker sky before it sets. The following events mark Venus’ appearance in the evening sky for the rest of 2013 until it passes inferior conjunction on January 11, 2014 and moves into the morning sky. All events are in the western evening sky:

The chart above shows Venus’ setting position in the western sky. (Click the image to see it larger.) The directions are represented by 180 degrees, south; 270 degrees, west. Venus sets north of west from the time it appears in the evening sky until mid-August 2013. It sets farthest north of west during June. From mid-August until it disappears back into bright, it sets south of west, reaching its most southern setting point during the first week of November.
