The planets Venus, Jupiter and Mars will make a close approach, passing within 1°09' of each other.
From Fairfield , the trio will become visible at around 20:50 (EDT), 25° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 2 hours and 44 minutes after the Sun at 23:14.
Venus will be at mag -4.3; Jupiter will be at mag -1.8; and Mars will be at mag 1.7. The trio will lie in the constellation Cancer.
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 Venus and Jupiter 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 |
| Venus | 09h00m50s | 18°56'N | Cancer | -4.3 | 24"9 |
| Jupiter | 08h59m10s | 17°52'N | Cancer | -1.8 | 32"1 |
| Mars | 09h00m10s | 18°25'N | Cancer | 1.7 | 4"3 |
The coordinates above are given in J2000.0. The trio will be at an angular separation of 45° from the Sun, which is in Taurus at this time of year.
