Mercury and Uranus will share the same right ascension, with Mercury passing 2°08' to the north of Uranus.
From Ashburn, the pair will be difficult to observe as they will appear no higher than 9° above the horizon. They will become visible around 20:10 (EDT) as the dusk sky fades, 9° above your western horizon. They will then sink towards the horizon, setting 1 hour and 14 minutes after the Sun at 21:04.
Mercury will be at mag -1.0, and Uranus at mag 5.9, both in the constellation Aries.
The pair will be too widely separated to fit within the field of view of a telescope, but will be visible through a pair of binoculars.
A graph of the angular separation between Mercury and Uranus around the time of closest approach is available here.
The positions of the two objects at the moment of conjunction 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 16° from the Sun, which is in Pisces at this time of year.

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.
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.
