The Moon and Mars will share the same right ascension, with the Moon passing 53' to the north of Mars. The Moon will be 15 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 between 16:49 and 06:45. They will become accessible at around 16:49, when they rise to an altitude of 7° above your north-eastern horizon. They will reach their highest point in the sky at 23:47, 74° above your southern horizon. They will become inaccessible at around 06:45 when they sink below 7° above your north-western horizon.
The Moon will be at mag -12.8, and Mars at mag -1.6, both in the constellation Gemini.
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 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 | 06h12m20s | 27°38'N | Gemini | -12.8 | 32'52"8 |
| Mars | 06h12m20s | 26°44'N | Gemini | -1.6 | 15"8 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 175° from the Sun, which is in Sagittarius at this time of year.
