Conjunction of Venus and Neptune

From the Conjunctions feed


Venus and Neptune will share the same right ascension, with Venus passing 30' to the south of Neptune.

From South El Monte however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 3° above the horizon at dawn.

Venus will be at mag -3.9, and Neptune at mag 8.0, both in the constellation Capricornus.

The pair will be a little too widely separated to fit comfortably within the field of view of a telescope, but will 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 20h29m30s 19°16'S Capricornus -3.9 11"6
Neptune 20h29m30s 18°46'S Capricornus 8.0 2"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 27° from the Sun, which is in Aquarius 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.
