Mars and Saturn will make a close approach, passing within 4°21' of each other.

From Ashburn (click to change), the pair will become visible at around 20:14 (EDT) as the dusk sky fades, 29° above your southern horizon. They will then sink towards the horizon, setting 4 hours and 36 minutes after the Sun at 00:25.

Mars will be at mag -0.4, and Saturn at mag 0.2, both in the constellation Ophiuchus.

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.

At around the same time, the two objects will also share the same right ascension – called a conjunction.

A graph of the angular separation between Mars and Saturn around the time of closest approach is available here.

The positions of the two objects at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Mars 16h30m30s -24°39' Ophiuchus -0.4 10"9
Saturn 16h32m50s -20°20' Ophiuchus 0.2 16"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 98° from the Sun, which is in Leo at this time of year.
