However, this example of legal political patronage can very easily become an example of corruption. If, while campaigning for governor, the candidate asked for someone's support in exchange for a position in his or her administration, this would be an act of illegal patronage.
A solar eclipse happens when the moon blocks the sun from the earth, and a lunar eclipse when the earth blocks the sun from the moon. Because the apparent diameter (how big it looks) of the moon is about the same as the sun, the alignment of the earth, moon and sun have to be almost perfect for a solar eclipse to occur.
Solar eclipses are relatively rare; they happen when the Moon moves directly and precisely in front of the Sun. Why are they so infrequent, and why do solar eclipses always come in pairs with lunar eclipses? It is all down to a mix of orbital alignments and cosmic coincidences.
