The Moon and Mars will make a close approach, passing within 3°25' of each other. The Moon will be 23 days old.

From Los Angeles , the pair will be visible in the dawn sky, rising at 01:34 (PDT) and reaching an altitude of 40° above the southern horizon before fading from view as dawn breaks at around 06:17.

The Moon will be at mag -11.5; and Mars will be at mag 1.2. Both objects will lie in the constellation Libra.

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 Mars 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 14h55m00s 11°52'S Libra -11.5 30'35"4
Mars 14h50m20s 15°06'S Libra 1.2 5"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 73° from the Sun, which is in Sagittarius at this time of year.
