Mars and Uranus will share the same right ascension, with Mars passing 0°37' to the north of Uranus.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Ashburn, the pair will become visible at around 18:37 (EDT) as the dusk sky fades, 32° above your western horizon. They will then sink towards the horizon, setting 3 hours and 33 minutes after the Sun at 21:29.

Mars will be at mag 1.3, and Uranus at mag 5.9, both in the constellation Pisces.

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 conjunction will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Mars 01h21m20s +08°34' Pisces 1.3 4"6
Uranus 01h21m20s +07°57' Pisces 5.9 3"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 43° from the Sun, which is in Aquarius at this time of year.
