The Moon and Mars will share the same right ascension, with the Moon passing 8'23" to the north of Mars. The Moon will be 25 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 difficult to observe as they will appear no higher than 13° above the horizon. They will be visible in the dawn sky, rising at 03:13 (EDT) – 2 hours and 5 minutes before the Sun – and reaching an altitude of 13° above the eastern horizon before fading from view as dawn breaks at around 04:32.
The Moon will be at mag -10.8, and Mars at mag 1.0, both in the constellation Cetus.
The pair will be close enough to fit within the field of view of a telescope, but will also be visible to the naked eye or through a pair of binoculars.
A graph of the angular separation between the Moon and Mars 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 | 00h31m00s | 1°56'N | Cetus | -10.8 | 30'37"9 |
| Mars | 00h31m00s | 1°47'N | Cetus | 1.0 | 5"3 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 52° from the Sun, which is in Taurus at this time of year.
