Mars and Uranus will make a close approach, passing within 0°58' of each other.
From Fairfield, the pair will become visible at around 17:59 (EDT) as the dusk sky fades, 50° above your south-western horizon. They will then sink towards the horizon, setting 5 hours and 29 minutes after the Sun at 22:47.
Mars will be at mag 1.0, and Uranus at mag 5.8, both in the constellation Aries.
The pair will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible through a pair of binoculars.
A graph of the angular separation between Mars and Uranus around the time of closest approach is available here.
The positions of the two objects 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 pair will be at an angular separation of 64° from the Sun, which is in Capricornus at this time of year.

The circumstances of this event were computed using the DE405 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.
