Conjunction of Mars and Uranus

Mars and Uranus will share the same right ascension, with Mars passing 2°50' to the north of Uranus.

From South El Monte , the pair will be visible in the evening sky, becoming accessible around 18:40 (PDT), 73° above your south-eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 19:41, 79° above your southern horizon. They will continue to be observable until around 01:00, when they sink below 20° above your western horizon.

Mars will be at mag -0.1, and Uranus at mag 5.5, both in the constellation Gemini.

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 06h26m40s 26°28'N Gemini -0.1 9"9
Uranus 06h26m40s 23°37'N Gemini 5.5 3"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 117° from the Sun, which is in Aquarius at this time of year.
