Mars and Uranus will make a close approach, passing within 0°58' of each other.

From Seattle, the pair will become visible around 18:12 (PDT) as the dusk sky fades, 47° above your south-western horizon. They will then sink towards the horizon, setting at 23:17.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

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.

At around the same time, the two objects will also share the same right ascension – called a conjunction.

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
Mars 01h46m50s +11°31' Aries 1.0 5"7
Uranus 01h48m10s +10°37' Aries 5.8 3"4

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.
