I love moon and like watching moon.
In summer and in winter.
The Moon is Earth's only natural satellite.
The average centre-to-centre distance from the Earth to the Moon is 384,403 kilometres, which is about 30 times the diameter of the Earth.
This the volume of the Moon is only 1/50th that of Earth.
The gravitational pull at its surface is about a 1/6th of Earth's.
The Moon makes a complete orbit around the Earth every 27.3 days, and the periodic variations in the geometry of the Earth–Moon–Sun system are responsible for the lunar phases that repeat every 29.5 days.
Not 30 days ..not 31 days.
