Other kinds of eclipses include those of the Sun by Mercury or Venus (transits), of distant stars by planets or planetary satellites (occultations) and of stars by orbiting companion stars.ĥ. Lunar eclipses occur twice in most years. When Earth is closest to the Sun and the Moon farthest from Earth, the Moon's silhouette may fall entirely within the Sun's disk, with a ring of the disk visible around it (annular eclipse). Solar eclipses visible from different parts of Earth occur two to five times a year one total solar eclipse occurs in most years. The shadow cast by the eclipsing body consists of the central umbra, into which no direct sunlight penetrates (total eclipse) and the encircling penumbra, reached by light from only part of the Sun's disk (partial eclipse). Observers along the shadow's path see a total or partial obscuring of the Sun's disk by the Moon's silhouette.
