Explanation:
Every Full Moon of 2021 shines in this year-spanning astrophoto project,  
a composite portrait of  
the familiar lunar nearside at each brightest  
lunar phase.  
  
Arranged by moonth,  
the year progresses in stripes beginning at the top.  
  
Taken with the same camera and lens the stripes are from Full Moon  
images all combined at the same pixel scale.  
  
The stripes still looked mismatched, but they show  
that the Full Moon's angular size changes throughout the year  
depending on its  
distance from Kolkata, India, planet Earth.  
  
The  
calendar month,  
a full moon name, distance in kilometers, and angular  
size is indicated for each stripe.  
  
Angular size is given in minutes of arc corresponding to 1/60th of a degree.  
  
The largest Full Moon is  
near a perigee or closest approach  
in May.  
  
The smallest is  
near an apogee,  
the most distant Full Moon in December.  
  
Of course the full moons of  
May and November  
also slid into Earth's shadow  
during 2021's two lunar eclipses.
