Studying the Sun’s effects helps us to understand the Moon better. For example, when the Sun sets and night falls on the Moon, some spots cool down faster than others.
Moon Phases - NASA Science
网页The Sun always illuminates half of the Moon while the other half remains dark, but how much we are able to see of that illuminated half changes as the Moon travels through its orbit. This graphic shows the position of the Moon and the Sun during each of the Moon’s phases and the Moon as it appears from Earth during each phase.
The phases of the Moon explained | The Planetary Society
网页2023年4月25日 · The phases of the Moon are caused by the changing positions of the Moon, Earth, and the Sun. As the Moon goes around the Earth, different parts of it are illuminated by the Sun. But because the same side of the Moon always points toward Earth, most of the time some of the illuminated part (daytime on the Moon) faces away from us.
