The planets Mars and Uranus will make a close approach, passing within a mere 32.1 arcminutes of each other.

From Fairfield, the pair will be visible in the dawn sky, rising at 01:42 (EDT) – 3 hours and 49 minutes before the Sun – and reaching an altitude of 33° above the eastern horizon before fading from view as dawn breaks around 04:47.

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 0.9; and Uranus will be at mag 5.8. Both objects will lie in the constellation Taurus.

They 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 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 03h35m20s +18°28' Taurus 0.9 5"5
Uranus 03h34m50s +18°59' Taurus 5.8 3"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 57° from the Sun, which is in Gemini at this time of year.

The circumstances of this event were computed using the DE430 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.
