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. During a transit, Venus is visible as a small black circle moving across the face of the Sun. Transits of Venus reoccur periodically.
In astronomy, planetary transits and occultations occur when a planet passes in front of another object, as seen by an observer.The occulted object may be a distant star, but in rare cases it may be another planet, in which case the event is called a mutual planetary occultation or mutual planetary transit, depending on the relative apparent diameters of the objects.
Transiting Venus is at its peak for about two days, and usually indicates feelings of love. Sometimes the influence is financial through receiving gifts or money. Transits to the sun and ascendant indicate a good time to buy new clothes or to beautify yourself, and transits to the moon a good time to beautify the home and buy new household goods.
Transits of Venus directly between the Earth and the Sun's visible disc are rare astronomical events. The first such transit to be predicted and observed was the 1639 transit of Venus, seen and recorded by English astronomers Jeremiah Horrocks and William Crabtree. [18]
The black drop effect was long thought to be due to Venus's thick atmosphere, and indeed it was held to be the first real evidence that Venus had an atmosphere. However, it is now thought by many to be an optical effect caused by the combination of the extreme darkening of the Sun's disk near its apparent edge and the intrinsic imperfection of ...

Venus was 0.7205 au from the Sun on the day of transit, decidedly less than average. [9] Moving far backwards in time, more than 200,000 years ago Venus sometimes passed by at a distance from Earth of barely less than 38 million km, and will next do that after more than 400,000 years.
