Mars and M22 will make a close approach, passing within 0°20' of each other.
From Ashburn, the pair will be visible in the dawn sky, rising at 03:37 (EST) – 3 hours and 9 minutes before the Sun – and reaching an altitude of 20° above the south-eastern horizon before fading from view as dawn breaks around 06:07.
Mars will be at mag 1.1, and M22 at mag 5.2, both in the constellation Sagittarius.
The pair will be close enough to fit within the field of view of a telescope, but will also be visible through a pair of binoculars.
A graph of the angular separation between Mars and M22 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|
The coordinates above are given in J2000.0. The pair will be at an angular separation of 61° from the Sun, which is in Aquarius 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.
