The Moon, Venus and Mars will make a close approach, passing within 2°30' of each other. The Moon will be 26 days old.
From Cambridge , the trio will be visible in the dawn sky, rising at 03:28 (EDT) – 3 hours and 43 minutes before the Sun – and reaching an altitude of 25° above the south-eastern horizon before fading from view as dawn breaks at around 06:51.
The Moon will be at mag -10.7; Venus will be at mag -4.4; and Mars will be at mag 1.5. The trio will lie in the constellation Libra.
They will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.
At around the same time, the trio will also share the same right ascension – called a conjunction.
A graph of the angular separation between the Moon and Venus around the time of closest approach is available here.
The positions of the trio at the moment of closest approach will be as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| The Moon | 15h36m00s | 14°28'S | Libra | -10.7 | 29'25"9 |
| Venus | 15h43m00s | 16°18'S | Libra | -4.4 | 23"7 |
| Mars | 15h32m20s | 18°34'S | Libra | 1.5 | 4"5 |
The coordinates above are given in J2000.0. The trio will be at an angular separation of 49° from the Sun, which is in Sagittarius at this time of year.
