The Moon and Venus will make a close approach, passing within 2°15' of each other. The Moon will be 26 days old.

From Cambridge , the pair will be visible in the dawn sky, rising at 03:23 (EST) – 1 hour and 51 minutes before the Sun – and reaching an altitude of 16° above the eastern horizon before fading from view as dawn breaks at around 04:54.

The Moon will be at mag -10.7; and Venus will be at mag -4.4. Both objects will lie in the constellation Pisces.

They 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.

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 01h04m40s 2°52'N Pisces -10.7 32'27"9
Venus 01h01m40s 4°59'N Pisces -4.4 27"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 45° from the Sun, which is in Taurus at this time of year.
