The Old Good Rocky friends of Earth -> THE MOON
 
Behold ~~ our Earth's natural satellite, the moon!

Enjoy :) !
 

 
The moon appears whitish-grey colour during the day and whitish-yellow during the night. It has some patches of dark region whom astronomers called them as "mare".
 
Do you know that the apparent size of the moon viewed from our Earth is smaller than our pinkies fingers ? According to measurement made by scientist, the angular size of the moon is 36' 20" and this value varies over time.
 
It's because of the revolving track of the moon around the Earth is actually an ellipse! Hence, there will be times when the Moon approaches the Earth at its nearest and farthest.
 
Nearest >> perigee
Farthest >> apogee
 
* These are the words from Greek which are used to describe the location of the celestial bodies.

[~~~THE AMAZING ORBITAL PERIOD of the MOON~~~]
 
Someone may ask : " Why does the surface of the moon that faces us is always the same ? "
 
Well, this is due to the fact that the rotational period of the moon is synchronised with its revolution period around the Earth, hence the side of the Moon that we see is always facing towards us.
