The moon is the only natural satellite of the earth and is the fifth largest moon in the solar system. The presence of the moon helps to stabilize the movement of our planet and to mitigate our climate.



238000 miles from the earth:

Size: With a diameter of 2,159 miles (3,475 km), the moon is only a quarter of the size of the earth.


Distance from Earth: The average distance of the Moon from the Earth is 238,000 miles (383,500 kilometers).


Orbit around the Earth: It takes 27.3 Earth days for the Moon to revolve around our planet once.


Rotation: The Moon revolves on its axis once every 27.3 Earth days.


Surface: The surface of the moon is covered by creeks, mountain ranges, rails (long narrow canals), and lava plains. The vast, dark areas we see on the surface of the moon are called Maria or the sea. They are very large, smooth lava beds. The bright, light areas on the surface of the moon are called highlands.


The moon is covered with a thick solid, rocky layer of about 500 miles (800 km).

Below the crust, scientists believe, is a partially molten zone that leads to a small iron core. Pits on the moon come in different sizes. The largest crater covers 1,600 miles (2,575 km), while the smallest crater is about the size of a pin.


Atmosphere: The moon has no lasting, important atmosphere, so the footprints of Apollo astronauts will last a long time.


Temperature: The average daytime temperature is 225 ° F (107 ° C), while the average nighttime temperature is -243 ° (-153 ° C).

Escape speed: To avoid the moon's gravity, you have to travel 5,200 miles (8,400 kilometers) per hour, while to escape the Earth's gravity you need to travel 25,000 miles (40,200 kilometers) per hour. Moon gravity is 6 times lighter than earth.
