Moon or Sun apparent size varies directly with nearness to horizon {Moon illusion}, until sufficiently above horizon. On horizon, Moon is redder, hazier, lower contrast, and fuzzier edged and has different texture. All these factors affect perceived distance.
elevation
Horizon Moon dominates and elevates scene, but scene seems lower when Moon is higher in sky.
distance
Horizon Moon, blue or black sky, and horizon are apparently at same place. Risen Moon appears in front of black night sky or blue day sky, because it covers blue or black and there is no apparent horizon.
topographic map
Moon illusion and other perspective illusions cause visual-brain topographic image to enlarge or shrink, whereas retinal image is the same.
