A transit of Venus takes place when Venus passes directly between the Sun and the Earth (or any other superior planet), becoming visible against (and hence obscuring a small portion of) the solar disk.

In the case of Venus, there are on average two transits every one and a quarter centuries. A transit of Venus occurs only if the planet is in inferior conjunction with the Sun (between Earth and Sun) and is also crossing the through Earth's orbital plane (the Ecliptic).

2012年5月30日 · For a transit of Venus to occur, two events must occur simultaneously, and it's rare to have such perfect synchrony. Transits of Venus can only occur when Venus passes between the Sun and Earth, a point on its orbit known as inferior conjunction.

2012年6月2日 · When Venus crosses in front of the sun, astronomers refer to this as a "transit." As the planet moves along its orbital path, it will travel across the solar disk, making it appear to observers...

2024年4月12日 · The Transit of Venus is a rare astronomical event in which the planet Venus passes directly between the Earth and the Sun, appearing as a small black dot moving across the face of the Sun. This phenomenon occurs when Venus is in inferior conjunction with the Sun, meaning it is positioned between the Earth and the Sun.

A Venus transit is a phenomenon in which the disk of the planet Venus passes like a small shadow across the face of the Sun. The transit can be seen (with proper protection!) by the unaided eye and looks something like a moving sunspot.

In astronomy, a 'transit' occurs when a smaller body passes in front of a larger one. A 'Transit of Venus' happens when Venus is seen in silhouette against the bright face of the Sun. Although Venus, the Earth and the Sun roughly line up every 584 days, the alignment is not usually precise.

Imagine two different people, one on each pole of the Earth, viewing the transit of Venus. The person on the North pole sees Venus following one path across the Sun. The person on the South pole sees Venus follow a slightly higher path, one that's shifted a little to the north.

What is the Transit of Venus? Planet Venus, courtesy of NASA. There have been fifty-two transits of Venus across the face of the Sun since 2000 B.C., but until 1643 A.D., no human was known to have observed this astronomical rarity.
