Apparent diameter plot for the Moon 2017-2018

This blog post was published 8 years ago and may or may not have aged well. While reading please keep in mind that it may no longer be accurate or even relevant.

The apparent diameter of the Moon varies with the Earth-Moon distance. Depending on the distance, the apparent angular diameter of the Moon is between 29.4 and 33.5 arcminutes.

For best astrophotography results, one should pick a time when the moon is closest. Similar to my plot of the apparent size of Venus, I wrote a short program to plot the Moon’s apparent diameter (see featured image).
