Transit of Venus - Simultaneous transits

A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and the Earth, obscuring a small portion of the Sun's disc. During a transit, Venus can be seen from the Earth as a small black disc moving across the face of the Sun. The duration of such transits is usually measured in hours (the transits of 2004 and 2012 last about six hours). A transit is similar to a solar eclipse by the Moon, but, although the diameter of Venus is almost 4 times that of the Moon, Venus appears much smaller because ...

The simultaneous occurrence of a transit of Mercury and a transit of Venus is possible, but only in the distant future. Such an event will next occur only in the years 69163 and 224508. The simultaneous occurrence of a solar eclipse and a transit of Venus is currently possible, but very rare. The next solar eclipse occurring during a transit of Venus will be on April 5 15232. Only 5 hours after the transit of Venus on June 4, 1769 there was a total solar eclipse, which was visible in Northern America, Europe and Northern Asia almost as partial solar eclipse. This was the lowest time difference between a trans ...

Apart from its rarity, the original scientific interest in observing a transit of Venus was that it could be used to determine the size of the solar system. The technique is to make precise observations of the slight difference in the time of either the start or the end of the transit from widely separated points on the Earth. The distance between the points on the Earth can then be used as a yard stick for the distance to Venus and the Sun. See "parallax". Although by the 17th century astronomers could calculate each planet's relativ ...

Sometimes Venus only grazes the Sun during a transit. In this case it is possible that in some areas of the Earth a full transit can be seen while in other regions there is only a partial transit (no second or fourth contact). The last transit of this type was on December 6th, 1631, while the next such transit will occur on December 13th, 2611. It is also possible that a transit of Venus can be seen in some parts of the world as a partial transit, while in others Venus misses the Sun. Such a transit last occurred on November 19th, 541BC, and th ...

In many cultures of the world, the transit of Venus across the Sun has been regarded as a rare and therefore an important event that marks major changes in human history. This is true for the Maya and other ancient American civilizations, for the Indian Vedic traditions and for the Western astrology of Mesopotamian origin. It has been claimed that a transit led to the ancient Greeks celebrating the Ancient Olympics every four years as a form of commemoration. The efforts of Guillaume Le Gentil to observe the transit of Venus in different parts of the globe, became the subject of the fictiona ...

Normally when the Earth and Venus are in conjunction they are not aligned with the Sun. Venus' orbit is inclined by 3.4° to the Earth's so it appears to pass under (or over) the Sun in the sky. Transits occur when the two planets happen to be in conjunction at (or very near) the points where their orbital planes cross. Although 3.4° may not seem like much, Venus can be as far as 9.6° from the Sun when viewed from the Earth at inferior conjunction. Since the angular diameter of the Sun is about half a degree, Venus may appear to pass above or below ...
