Fascinating Facts About the Moon

There are facts about the Moon you probably know because the Moon has featured in myths and legends throughout history and blood moons have recently become popular news items. Historically staring at the moon was said to send you mad and people went to great lengths to prevent the moon shining on their faces while they slept. Lunar is the adjective relating to the Moon from which the word lunatic, for mentally ill people, and moonstruck are derived. As recently as 1700, people still believed the Moon caused fever, epilepsy and other illnesses. In 2012 President Obama finally put a stop to this lunacy, at least in the US, by removing the term lunatic from laws. Here’s a B&W image of a Blood moon was taken by Al Goold Photography on 14th April 2014.

Density3.34 g/cm3 (compared to Earth’s 5.5 g/cm3)
Volume5277 million sq miles (2195 x 1010 km3), approx. 2% Earth’s volume.
Surface area14.7 million sq miles (37.9 million sq km).
ColorDark gray surface (despite appearing white).
Physical characteristicsLarge dark plains known as Maria, from Mare – sea in Latin. Mostly resulting from the impact of rubble from space. Craters up to 15,000 feet (4500m) deep.
