The Moon and Venus will make a close approach, passing within 0°58' of each other. The Moon will be 3 days old.
From Washington, the pair will become visible around 17:42 (MDT) as the dusk sky fades, 22° above your south-western horizon. They will then sink towards the horizon, setting 2 hours and 39 minutes after the Sun at 20:01.
The Moon will be at mag -10.0, and Venus at mag -4.0, 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 to the naked eye or through a pair of binoculars.
At around the same time, the two objects will also share the same right ascension – called a conjunction.
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 Moon | 20h54m50s | -20°20' | Capricornus | -10.0 | 30'10"4 |
| Venus | 20h54m10s | -19°22' | Capricornus | -4.0 | 12"8 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 33° from the Sun, which is in Sagittarius at this time of year.
