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.
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 Transit of Venus, 1639, seen and recorded by English astronomers Jeremiah Horrocks and William Crabtree. [17]
Missions to Venus constitute part of the exploration of Venus. The Soviet Union , followed by the United States , have soft landed probes on the surface. Venera 7 was the first lander overall and first for the Soviet Union, touching down on 15 December 1970.
On 16 February 1768 the Royal Society petitioned King George III to finance a scientific expedition to the Pacific to study and observe the 1769 transit of Venus across the face of the sun to enable the measurement of the distance from the Earth to the Sun. [2] Royal approval was granted for the expedition, and the Admiralty elected to combine the scientific voyage with a confidential mission ...

1761 – Mikhail Lomonosov is the first to discover and appreciate the atmosphere of Venus during his observation of the transit of Venus. [116] 1766 – Johann Titius finds the Titius-Bode rule for planetary distances. [117] 1772 – Johann Bode publishes the Titius-Bode rule for planetary distances. [117]
2012 transit of Venus, projected to a white card by a telescope. A transit of Venus is the appearance of Venus in front of the Sun, during inferior conjunction. Since the orbit of Venus is slightly inclined relative to Earth's orbit, most inferior conjunctions with Earth, which occur every synodic period of 1.6 years, do not produce a transit ...
The next time a mutual planetary transit or occultation will happen (as seen from Earth) will be on 22 November 2065 at about 12:43 UTC, when Venus near superior conjunction (with an angular diameter of 10.6") will transit in front of Jupiter (with an angular diameter of 30.9"); however, this will take place only 8° west of the Sun, and will therefore not be visible to the unaided/unprotected ...
