===Lunar eclipses===
When the Moon moves into [[Earth's shadow]], a [[lunar eclipse]] occurs, during which all or part of the Moon's face may appear reddish due to the [[Rayleigh scattering]] of blue wavelengths and the [[atmospheric refraction|refraction]] of [[sunlight]] through [[Atmosphere of Earth|Earth's atmosphere]].<ref>{{cite book |first=P.

A lunar eclipse does not occur every month because the Moon's orbit is [[orbital inclination|inclined]] 5.145° with respect to the [[ecliptic]] plane of Earth; thus, the Moon usually passes north or south of Earth's shadow, which is mostly restricted to this [[plane of reference]]. Lunar eclipses happen only when the full moon occurs around either [[orbital node|node of its orbit]] (ascending or descending). Therefore, a lunar eclipse occurs about every six months, and often two weeks before or after a [[solar eclipse]], which occurs during a [[new moon]] around the opposite node.
