==Passing closer==
[[File:ESO’s Very Large Telescope (VLT) observatory at Paranal.jpg|thumb|In the night sky over [[ESO]]'s [[Very Large Telescope]] (VLT) observatory at [[Paranal Observatory|Paranal]], the [[Moon]] shines along with two bright companions: [[Venus]] and [[Jupiter]].]]
However, if two celestial bodies attain the same [[declination]] at the time of a conjunction in [[right ascension]] (or the same ecliptic latitude at a conjunction in ecliptic longitude), the one that is closer to the Earth will pass in front of the other. In such a case, a [[Syzygy (astronomy)|syzygy]] takes place. If one object moves into the shadow of another, the event is an [[eclipse]]. For example, if the Moon passes into the shadow of Earth and disappears from view, this event is called a [[lunar eclipse]]. If the visible disk of the nearer object is considerably smaller than that of the farther object, the event is called a [[Astronomical transit|transit]]. When Mercury passes in front of the Sun, it is a [[transit of Mercury]], and when Venus passes in front of the Sun, it is a [[transit of Venus]]. When the nearer object appears larger than the farther one, it will completely obscure its smaller companion; this is called an [[occultation]]. An example of an occultation is when the Moon passes between Earth and the Sun, causing the Sun to disappear either entirely or partially. This phenomenon is commonly known as a [[solar eclipse]]. Occultations in which the larger body is neither the Sun nor the Moon are very rare. More frequent, however, is an occultation of a planet by the [[Moon]]. Several such events are visible every year from various places on Earth.
