Venus and Neptune will share the same right ascension, with Venus passing 2°03' to the north of Neptune.

From San Diego 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.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

Venus will be at mag -4.5, and Neptune at mag 7.9, both in the constellation Pisces.

The pair will be too widely separated to fit 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 00h05m00s 1°12'N Pisces -4.5 34"7
Neptune 00h05m00s 0°50'S Pisces 7.9 2"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 41° from the Sun, which is in Aries at this time of year.
