Eclipse
From Wikipedia, the free encyclopedia
For other uses, see Eclipse (disambiguation).
An eclipse is an astronomical event. It is a process that develops slowly across time.
The eclipse is when one object in the sky moves into the shadow of another such object. When an eclipse happpens within a system of stars, like the Solar System, it makes a type of syzygy. This means that three or more objects in the sky are lined up in a straight line in the same gravitational system.[1]
The term eclipse is most often used to describe a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the shadow of Earth.
Etymology [change]
The word comes from the ancient Greek noun ἔκλειψις (ékleipsis), which is from the verb ἐκλείπω (ekleípō). This means "to cease (stop) to exist (be there)".[2][3][4]
