Lunar Eclipse
Lesson summary
Lesson summary
- The Moon reflects sunlight, and its phases repeat about every 29.5 days.
- A lunar eclipse happens when the Earth is between the Sun and the Moon, so the Moon enters the Earth’s shadow.
- A lunar eclipse happens at full moon, but not at every full moon because the Moon’s orbit is tilted.
- During a total lunar eclipse the Moon looks red, because of sunlight bent by the Earth’s atmosphere.
