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.
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 ...
Transit of Venus: 2492 May 6 Belgian astronomer Jean Meeus asserts that the orbits of all eight planets and Pluto will be within the same 90° arc of the Solar System. The last time this is believed to have occurred was on February 1, 949. [69] 2498 June 10 Transit of Venus. 2515 April 7 At 10:37 UTC, Mars will occult Neptune. [42] [70] 2518 ...
On August 23, 2023, Venus retrograde and Mercury retrograde will join forces for a wild and crazy finale to summer. As you look at your calendar to lock in your last-minute summer plans, there are ...
At their closest point, Jupiter and Venus will be just half a degree apart – about the diameter of a full moon – despite being more than 600 million km (400 million miles) away from each other ...
The transit of celestial objects is one of the few key phenomena used today for the study of exoplanetary systems. Today, transit photometry is the leading form of exoplanet discovery. [5] As an exoplanet moves in front of its host star there is a dimming in the luminosity of the host star that can be measured. [6]

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 ...
