Venus will pass very close to the Sun in the sky as its orbit carries it around the far side of the solar system from the Earth.

This occurs once in every synodic cycle of the planet (584 days), and marks the end of Venus's apparition in the morning sky and its transition to become an evening object over the next few weeks.

At closest approach, Venus will appear at a separation of only 0°46' from the Sun, making it totally unobservable for several weeks while it is lost in the Sun's glare.

Venus will also pass apogee – the time when it is most distant from the Earth – at around the same time, since it will lie exactly opposite to the Earth in the Solar System. It will move to a distance of 1.71 AU from the Earth, making it appear small and very distant. If it could be observed, it would measure 9.8 arcsec in diameter, whilst appearing completely illuminated.

The exact position of Venus at the moment it passes solar conjunction will be:

Object Right Ascension Declination Constellation Angular Size
Venus 19h21m20s -22°53' Sagittarius 9.8"
Sun 19h20m -22°08' Sagittarius 32'31"

The coordinates above are given in J2000.0.

Warning

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.

Source

The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
