Book 8, Question 42
Why Does Daylight on the Moon Last About Two Earth Weeks?
A day on the Moon lasts about two Earth weeks because the Moon spins very slowly! One lunar daytime is roughly 14 Earth days of sunlight, followed by about 14 days of night. A lunar day is not the same as an Earth day!
More fun facts
- Lunar day and night are each about two Earth weeks long.
- Earth and the Moon are traveling around the Sun together, so it takes a little more than two extra days for sunlight to hit the Moon the same way again.
- During a crescent Moon, it is night on most of the side facing us and day on most of the far side.
- In full sunlight the Moon's surface reaches about 260 degrees Fahrenheit, but in the long darkness it plunges to about minus 280 degrees Fahrenheit.
- A new Moon happens when the far side of the Moon is in full sunlight and the side facing us is having its night.
