The harvest moon is the full moon on a day nearest the first day of autumn. Full or nearly full, it rises early in the evening for several nights in a row. It brings farmers well-lit evenings to harvest their crops.
The harvest moon can look huge. But does it really fill more of the sky than an ordinary full moon?
Why does the moon look bigger when it is near the horizon? Our brains compare the size of the moon with the size of the objects we see on the horizon.
