Jupiter and Mars will make a close approach, passing within 0°47' of each other.
From Ashburn, 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 04:09 (EDT) – 1 hour and 53 minutes before the Sun – and reaching an altitude of 15° above the eastern horizon before fading from view as dawn breaks around 05:41.
Jupiter will be at mag -1.9; and Mars will be at mag 1.6. Both objects will lie in the constellation Gemini.
They will be a little too widely separated to fit comfortably 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 Jupiter 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|
The coordinates above are given in J2000.0. The pair will be at an angular separation of 23° from the Sun, which is in Cancer 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.
