However, it can also refer to such events beyond the Earth-Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its host planet, or a moon passing into the shadow of another moon. A binary star system can also produce eclipses if the plane of the orbit of its constituent stars intersects the observer's position. An eclipse is caused when an astrological object is covered by another. If the sun is covered by the moon, it is a solar eclipse. If the moon is covered by the sun, it is a lunar eclipse. An eclipse shrouds a certain area of about ? square kilometres in darkness for about ?. media type="custom" key="21148870"
