The Moon and Mars will make a close approach, passing within 6°37' of each other. The Moon will be 14 days old.
From Cambridge , the pair will be visible between 19:47 and 06:06. They will become accessible at around 19:47, when they rise to an altitude of 7° above your eastern horizon. They will reach their highest point in the sky at 00:57, 45° above your southern horizon. They will become inaccessible at around 06:06 when they sink below 7° above your western horizon.
The Moon will be at mag -12.8 in Pisces; and Mars will be at mag -2.8 in Cetus.
They 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.
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 | 00h17m00s | 3°56'N | Pisces | -12.8 | 33'19"9 |
| Mars | 00h29m30s | 1°54'S | Cetus | -2.8 | 23"7 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 177° from the Sun, which is in Virgo at this time of year.
