The Moon and Venus will make a close approach, passing within 0°58' of each other. The Moon will be 3 days old.
From Cambridge, the pair will be difficult to observe as they will appear no higher than 19° above the horizon. They will become visible around 16:40 (EST) as the dusk sky fades, 19° above your south-western horizon. They will then sink towards the horizon, setting 2 hours and 42 minutes after the Sun at 19:00.
The Moon will be at mag -10.0; and Venus will be at mag -4.0. Both objects will lie in the constellation Capricornus.
They 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 pair 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 pair 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.
