Mars and Uranus will make a close approach, passing within 1°18' of each other.

From Cambridge, the pair will be visible in the dawn sky, rising at 23:57 (EST) and reaching an altitude of 53° above the south-eastern horizon before fading from view as dawn breaks around 05:04.

Mars will be at mag 0.2; and Uranus will be at mag 5.8. Both objects will lie in the constellation Aries.

They will be too widely separated to fit within the field of view of a telescope, but will be visible through a pair of binoculars.

At around the same time, the pair 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 pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Mars 03h05m40s +15°41' Aries 0.2 8"3
Uranus 03h04m10s +16°57' Aries 5.8 3"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 81° from the Sun, which is in Cancer at this time of year.

The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
