The Moon and Mars will make a close approach, passing within a mere 1.5 arcminutes of each other. From some parts of the world, the Moon will pass in front of Mars, creating a lunar occultation. The Moon will be 18 days old.
From Cambridge , the pair will be visible in the morning sky, becoming accessible around 21:49, when they reach an altitude of 7° above your eastern horizon. They will then reach their highest point in the sky at 03:30, 54° above your southern horizon. They will be lost to dawn twilight around 05:55, 42° above your south-western horizon.
The Moon will be at mag -12.3; and Mars will be at mag -1.9. Both objects will lie in the constellation Pisces.
They 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.
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 | 01h49m10s | 6°43'N | Pisces | -12.3 | 29'26"7 |
| Mars | 01h49m10s | 6°41'N | Pisces | -1.9 | 19"6 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 135° from the Sun, which is in Leo at this time of year.
