Conjunction of Mars and Uranus

Mars and Uranus will share the same right ascension, with Mars passing 1°02' to the north of Uranus.

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

From South El Monte , the pair will be visible in the dawn sky, rising at 01:20 (PDT) and reaching an altitude of 47° above the south-eastern horizon before fading from view as dawn breaks at around 05:29.

Mars will be at mag 1.4, and Uranus at mag 5.5, both in the constellation Virgo.

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 11h39m50s 4°01'N Virgo 1.4 5"2
Uranus 11h39m50s 2°59'N Virgo 5.5 3"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 65° from the Sun, which is in Libra at this time of year.
