The Moon and Mars will make a close approach, passing within a mere 24.6 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 25 days old.
From Columbus , the pair will be visible in the dawn sky, rising at 03:37 (EDT) and reaching an altitude of 25° above the south-eastern horizon before fading from view as dawn breaks at around 07:00.
The Moon will be at mag -11.3; and Mars will be at mag 1.3. Both objects will lie in the constellation Scorpius.
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 | 16h19m10s | 21°23'S | Scorpius | -11.3 | 32'00"7 |
| Mars | 16h19m40s | 21°00'S | Scorpius | 1.3 | 5"1 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 60° from the Sun, which is in Capricornus at this time of year.
