The only natural satellite of Earth, it displays only 59% of its surface to a terrestrial observer. This is due to the period of axial rotation being equal to that of orbit, a "captured rotation".
The hidden side was first scanned by the Russian sattellite Lunik III in October 1959.

All other numbers are composed of repetitions or combinations of these basic characters.
When a character is followed by one of lesser or equal value, the values are added.
When a character is preceded by one of a lesser value, the smaller is subtracted from the larger.

Light passing through a prism may be divided up into different colours.
This is due to the slight differences in refraction of each wavelength, or band of colour. The shortest visible light is violet, while the longest is red.
The commonly known colours of the rainbow as the effect is naturally observed are:
red, orange, yellow, green, blue, indigo and violet.
Another way to remember this is to think of the name ROY G. BIV, which represent first letters of each colour.
In reality there is a spectrum of colours that are conveniently classed by these common groupings.
