An enormous Moon

An enormous Moon

Fig. 5.6 . In this awesome picture, a man and child seem enveloped by the Earth’s Moon, which looks huge in comparison to the tree in the foreground. When the Moon is overhead, alone in an otherwise empty sky, there are no other objects to gauge its distance; we then think the Moon is smaller than at the horizon. (Courtesy of der Foto-Treff.)
