The planets Jupiter and Mars will make a close approach, passing within a mere 34.9 arcminutes of each other.

From San Diego, the pair will be visible in the dawn sky, rising at 02:29 (PST) – 3 hours and 11 minutes before the Sun – and reaching an altitude of 34° above the south-eastern horizon before fading from view as dawn breaks around 05:23.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

Jupiter will be at mag -2.3; and Mars will be at mag 0.7. 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 to the naked eye or 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 Jupiter and Mars 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
Jupiter 00h12m50s +00°08' Pisces -2.3 36"2
Mars 00h13m40s -00°23' Pisces 0.7 6"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 64° from the Sun, which is in Taurus 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.
