The planets Saturn and Mars will make a close approach, passing within 1°41' of each other.

From South El Monte , the pair will be difficult to observe as they will appear no higher than 15° above the horizon. They will be visible in the dawn sky, rising at 04:19 (PDT) – 2 hours and 8 minutes before the Sun – and reaching an altitude of 15° above the south-eastern horizon before fading from view as dawn breaks at around 05:42.

Saturn will be at mag 0.5; and Mars will be at mag 1.7. Both objects will lie in the constellation Libra.

They 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 pair will also share the same right ascension – called a conjunction.

A graph of the angular separation between Saturn 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
Saturn 14h26m40s 12°10'S Libra 0.5 15"5
Mars 14h24m20s 13°45'S Libra 1.7 3"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 25° from the Sun, which is in Scorpius at this time of year.

The circumstances of this event were computed using the DE440 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.
