The simultaneous occurrence of transits of Mercury and Venus does occur, but extremely infrequently. Such an event last occurred on 22 September 373,173 BC and will next occur on 26 July 69,163, [34] and again on 29 March 224,504. [35] The simultaneous occurrence of a solar eclipse and a transit of Venus is currently possible, but very rare ...
Conjunction (astronomy) Visual conjunction between the Moon and the planet Venus, the two brightest objects in the night sky. In astronomy, a conjunction occurs when two astronomical objects or spacecraft appear to be close to each other in the sky. This means they have either the same right ascension or the same ecliptic longitude, usually as ...
The orbit of Venus is 224.7 Earth days (7.4 avg. Earth months [30.4 days]). The phases of Venus result from the planet's orbit around the Sun inside the Earth's orbit giving the telescopic observer a sequence of progressive lighting similar in appearance to the Moon's phases. It presents a full image when it is on the opposite side of the Sun.
The last three features were named before the current system was adopted by the International Astronomical Union, the body which oversees planetary nomenclature. [48] The longitude of physical features on Venus is expressed relative to its prime meridian.
Indeed, between year 1 and 3000, the maximum conjunction distances were 1.3 degrees in 1306 and 1940. Conjunctions in both years occurred when the planets were tilted most out of the plane: longitude 206 degrees (therefore above the plane) in 1306, and longitude 39 degrees (therefore below the plane) in 1940.

Astronomers have calculated that a year on Venus is 225 Earth days, meaning that a year on Venus is actually shorter than a day on the planet. How's that for weird? This research will help to more ...
A long gap separates its period of current study after 1830 from its 17th century discovery. Whether the original spot dissipated and reformed, whether it faded, or if the observational record was simply poor is unknown. [6] The first sighting of the Great Red Spot is often credited to Robert Hooke, who described a spot on the planet in May 1664.
Fort Venus located on the north coast of Tahiti. On 3 June 1769, navigator Captain James Cook, naturalist Joseph Banks, astronomer Charles Green and naturalist Daniel Solander recorded the transit of Venus from the island of Tahiti during Cook's first voyage around the world. [1] During a transit, Venus appears as a small black disc travelling ...
