The Moon and Venus will make a close approach, passing within 1°50' of each other. The Moon will be 4 days old.
From Ashburn, the pair will become visible around 17:14 (EDT) as the dusk sky fades, 31° above your south-western horizon. They will then sink towards the horizon, setting 3 hours and 49 minutes after the Sun at 20:43.
The Moon will be at mag -10.7, and Venus at mag -4.4, both in the constellation Aquarius.
The pair will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.
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 closest approach will be as follows:
|Object||Right Ascension||Declination||Constellation||Magnitude||Angular Size|
The coordinates above are given in J2000.0. The pair will be at an angular separation of 47° from the Sun, which is in Sagittarius 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.
