Iapetus  

Définition

  • Iapetus is an outer moon of Saturn, also known as Saturn VII, that was discovered by Giovanni Cassini in 1671. It is remarkable in that its brightness changes by a factor of seven as it moves around its orbit – a feature that has led to it being called the "yin and yang" moon. Whereas the leading hemisphere of Iapetus is as dark as asphalt with a slight reddish color, the trailing hemisphere is very bright.
