The planets Mars and Uranus will make a close approach, passing within a mere 34.2 arcminutes of each other.

From Fairfield , the pair will become visible at around 18:45 (EDT), 27° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 3 hours and 38 minutes after the Sun at 21:18.

Mars will be at mag 1.3; and Uranus will be at mag 5.9. Both objects will lie in the constellation Pisces.

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 01h20m20s 8°28'N Pisces 1.3 4"6
Uranus 01h21m20s 7°57'N Pisces 5.9 3"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 43° from the Sun, which is in Aquarius 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.
