Conjunction of the Moon and Venus

The Moon and Venus will share the same right ascension, with the Moon passing 47' to the north of Venus. The Moon will be 27 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 be visible in the dawn sky, rising at 04:59 (EST) – 2 hours and 3 minutes before the Sun – and reaching an altitude of 15° above the south-eastern horizon before fading from view as dawn breaks at around 06:42.

The Moon will be at mag -9.5, and Venus at mag -4.0, both in the constellation Libra.

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.

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 15h36m50s 17°11'S Libra -9.5 33'00"8
Venus 15h36m50s 17°58'S Libra -4.0 11"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 25° from the Sun, which is in Ophiuchus at this time of year.
