Denebola size

Full Moon occurs at 10:54 . EST. The glowing orb stands in the far-southern part of Leo the Lion, between the constellations Virgo to the east and Sextans to the west. This lunar phase is the least interesting to observers because sunlight falls straight down on the Moon from our perspective, which minimizes shadow detail. So this might be a good night to observe the Moon illusion — the Full Moon appears larger when it’s near the horizon than when it stands high in the sky. But its size doesn’t change, and you can prove it with a single sheet of paper. Go out just after sunset and find the Moon low in the east. Roll the paper into a tube and change the tube’s diameter until the Moon just fills the field of view when you look through it. Tape the tube so its size doesn’t change. Then, head indoors and go back outside a few hours later when the Moon is high. Look through the tube again. The fact that the Moon will be the same size still amazes even seasoned observers. The best explanation for this illusion seems to be that when the Moon lies near the horizon, our brain compares its size with foreground objects, which don’t appear near the Moon when it’s high in the sky.
