The Moon and Venus will share the same right ascension, with the Moon passing 2°51' to the north of Venus. The Moon will be 3 days old.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From Cambridge , the pair will become visible at around 18:29 (EST), 12° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 1 hour and 48 minutes after the Sun at 19:59.
The Moon will be at mag -10.7, and Venus at mag -4.2, both in the constellation Scorpius.
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 conjunction will be as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| The Moon | 15h58m00s | 20°26'S | Scorpius | -10.7 | 32'48"0 |
| Venus | 15h58m00s | 23°17'S | Scorpius | -4.2 | 20"3 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 45° from the Sun, which is in Virgo at this time of year.
