Saturn and Mars will share the same right ascension, with Saturn passing 3°33' to the north of Mars.

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

From Fairfield, the pair will become visible around 20:07 (EDT) as the dusk sky fades, 23° above your south-western horizon. They will then sink towards the horizon, setting 3 hours and 8 minutes after the Sun at 22:41.

Saturn will be at mag 0.4, and Mars at mag 0.6, both in the constellation Libra.

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

A graph of the angular separation between Saturn and Mars 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
Saturn 15h02m50s -15°02' Libra 0.4 16"3
Mars 15h02m50s -18°36' Libra 0.6 6"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 73° from the Sun, which is in Leo 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.
