Conjunction of Venus and Neptune

Venus and Neptune will share the same right ascension, with Venus passing 1'33" to the north of Neptune.

From Fairfield however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 9° above the horizon at dawn.

Venus will be at mag -4.0, and Neptune at mag 8.0, both in the constellation Sagittarius.

The pair will be close enough to fit within the field of view of a telescope, but will also be visible through a pair of binoculars.

A graph of the angular separation between Venus and Neptune around the time of closest approach is available here.

The positions of the two objects at the moment of conjunction will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Venus 18h01m50s 22°15'S Sagittarius -4.0 13"2
Neptune 18h01m50s 22°16'S Sagittarius 8.0 2"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 34° from the Sun, which is in Capricornus at this time of year.

The circumstances of this event were computed using the DE430 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.
