Apparent diameter plot for Jupiter 2017-2026
Caveat Lector: This blog post was published 9 years ago. Depending on the content, it may no longer be applicable or relevant.
The apparent diameter of Jupiter varies with the Earth-Jupiter distance. Depending on the distance, the apparent angular diameter of Jupiter is between approx. 0.5 and 0.8 arcminutes.
For best astrophotography results, one should pick a time when Jupiter is closest. Similar to my plot of the apparent size of Venus, I wrote a short program to plot Jupiter’s apparent diameter for the time period 2017-2026 (see featured image).
