The Moon, Mars and Uranus will make a close approach, passing within 4°07' of each other. The Moon will be 3 days old.
From Fairfield, the trio will become visible around 18:02 (EDT), 35° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 3 hours and 32 minutes after the Sun at 21:18.
The Moon will be at mag -10.6; Mars will be at mag 1.3; and Uranus will be at mag 5.9. The trio will lie in the constellation Pisces.
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.
A graph of the angular separation between the Moon and Mars 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 coordinates above are given in J2000.0. The trio will be at an angular separation of 42° from the Sun, which is in Aquarius at this time of year.

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).
This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
