Venus and Neptune will make a close approach, passing within 0°04' of each other.

From Ashburn, the pair will become visible around 17:42 (EDT) as the dusk sky fades, 30° above your south-western horizon. They will then sink towards the horizon, setting 3 hours and 17 minutes after the Sun at 20:40.

Venus will be at mag -4.1; and Neptune will be at mag 7.9. Both objects will lie in the constellation Aquarius.

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

At around the same time, the pair will also share the same right ascension – called a conjunction.

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

The positions of the pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Venus 23h12m40s -06°15' Aquarius -4.1 14"9
Neptune 23h12m30s -06°11' Aquarius 7.9 2"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 39° from the Sun, which is in Capricornus at this time of year.
