The Moon and Venus will share the same right ascension, with the Moon passing 5°10' to the south of Venus. The Moon will be 26 days old.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Washington (click to change), the pair will be difficult to observe as they will appear no higher than 15° above the horizon. They will be visible in the dawn sky, rising at 05:06 (MDT) – 1 hour and 42 minutes before the Sun – and reach an altitude of 15° above the eastern horizon before fading from view as dawn breaks at around 06:30.

The Moon will be at mag -10.3 in the constellation Aquarius, and Venus at mag -4.5 in the neighbouring constellation of Pisces.

The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.

A graph of the angular separation between the Moon and Venus 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
The Moon 23h48m20s -03°34' Aquarius -10.3 32'06"7
Venus 23h48m20s +01°36' Pisces -4.5 42"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 37° from the Sun, which is in Aries at this time of year.

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.
