Mars and Uranus will share the same right ascension, with Mars passing 1°43' to the north of Uranus.

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

From Seattle, the pair will be visible in the evening sky, becoming accessible around 17:29 (PDT) as the dusk sky fades, 54° above your southern horizon. They will then reach its highest point in the sky at 18:19, 55° above your southern horizon. They will continue to be observable until around 00:19, when they sink below 10° above your western horizon.

Mars will be at mag 0.2, and Uranus at mag 5.8, 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 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 02h17m00s +14°58' Aries 0.2 8"5
Uranus 02h17m00s +13°15' Aries 5.8 3"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 95° from the Sun, which is in Capricornus at this time of year.
