Question

why the temperature of the moon falls to -190°c?​

Answer 1

Explanation:

Well, you're going to want to pack something to keep you warm, since the temperature of the Moon can dip down to -153°C during the night.

It happens because the Moon doesn't have an atmosphere like the Earth.

Here on Earth, the atmosphere acts like a blanket, trapping heat.

Answer 2

Explanation:

Since the temperature of the Moon can dip down to -153°C during the night. Oh, but you’re going to want to keep some cool weather clothes too, since the temperature of the Moon in the day can rise to 107°C.

It happens because the Moon doesn’t have an atmosphere like the Earth. Here on Earth, the atmosphere acts like a blanket, trapping heat. Sunlight passes through the atmosphere, and warms up the ground. The energy is emitted by the ground as infrared radiation, but it can’t escape through the atmosphere again easily so the planet warms up. Nights are colder than days, but it’s nothing like the Moon.

There’s another problem. The moon takes 27 days to rotate once on its axis. So any place on the surface of the Moon experiences about 13 days of sunlight, followed by 13 days of darkness. So if you were standing on the surface of the Moon in sunlight, the temperature would be hot enough to boil water. And then the Sun would go down, and the temperature would drop 250 degrees in just a matter of moments.
