A comparative image showcasing a first quarter moon (near perigee) and a third quarter moon (near apogee). The difference in apparent size, due to the Moon's elliptical orbit, is clearly visible when placed side-by-side, highlighting the varying distances between the Earth and the Moon throughout its orbit.
