Mars and M44 will make a close approach, passing within a mere 10.4 arcminutes of each other.
From Fairfield , the pair will become visible at around 21:36 (EDT), 26° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 3 hours and 46 minutes after the Sun at 00:05.
Mars will be at mag 1.6; and M44 will be at mag 3.1. Both objects will lie in the constellation Cancer.
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.
A graph of the angular separation between Mars and M44 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 |
| Mars | 08h40m30s | 19°50'N | Cancer | 1.6 | 4"6 |
| M44 | 08h40m20s | 19°40'N | Cancer | 3.1 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 55° from the Sun, which is in Taurus at this time of year.
