The Moon and Mars will share the same right ascension, with the Moon passing 7°05' to the south of Mars. The Moon will be 23 days old.
From Columbus , the pair will be visible in the dawn sky, rising at 01:00 (EDT) and reaching an altitude of 65° above the south-eastern horizon before fading from view as dawn breaks at around 07:19.
The Moon will be at mag -11.7, and Mars at mag 0.8, both in the constellation Cancer.
The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.
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 | 09h02m40s | 11°19'N | Cancer | -11.7 | 30'54"9 |
| Mars | 09h02m40s | 18°24'N | Cancer | 0.8 | 6"8 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 80° from the Sun, which is in Virgo at this time of year.
