Moon Profile

MOON PROFILE

NAME:  Moon of the Earth (Luna)

AGE: 4.51 billion years

ADD:

ROTATION PERIOD:  

The Moon appears to move completely around the celestial sphere once in about 27.3 days as observed from the Earth. This is called a sidereal month. It represents the orbital period of the Moon around the Earth.

REVOLUTION PERIOD: 27 days

SPECIAL CHARACTERISTIC:  

• The Moon is approximately 384,400 km (239,000 miles) from the Earth. A radio signal from the Earth and bounced off the Moon's surface back to Earth would take approximately 2 seconds. Communication with an astronaut on the Moon would thus have a several second pause between a question and an answer.                                      

• The diameter of the Moon is 3479 kilometers (2162 miles). This is about 1/4 the diameter of the Earth (12,756 kilometers or 7,926 miles).                                             

• The mass of the Moon is 7.35*10²² kilograms, which is about 1/80 of the mass of the Earth. (10²²is 10 times itself 21 times or 1 followed by 22 zeros.) The density of the Moon is 3340 kg/m³.The average temperature on the surface of the Moon during the day is 107°C. That is hot enough to boil water on the Earth. During the night, the average temperature drops to −153°C.

EFFECT (S) ON EARTH: 

The moon's gravity pulls at the Earth, causing predictable rises and falls in sea levels known as tides. ... Low tides occur between these two humps. The pull of the moon is also slowing the Earth's rotation, an effect known as tidal braking, which increases the length of our day by 2.3 milliseconds per century.
