Saturn and M22 will make a close approach, passing within 1°08' of each other.

From Fairfield , the pair will become visible at around 19:20 (EDT), 22° above your southern horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 22:28.

Saturn will be at mag 0.3; and M22 will be at mag 5.2. Both objects will lie in the constellation Sagittarius.

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

A graph of the angular separation between Saturn and M22 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 18h36m10s 22°45'S Sagittarius 0.3 16"2
M22 18h36m20s 23°54'S Sagittarius 5.2 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 76° from the Sun, which is in Virgo 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.
