Jupiter and Mercury will share the same right ascension, with Jupiter passing 13' to the north of Mercury.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From Columbus , the pair will be visible in the dawn sky, rising at 05:23 (EDT) – 1 hour and 27 minutes before the Sun – and reaching an altitude of 11° above the eastern horizon before fading from view as dawn breaks at around 06:30.
Jupiter will be at mag -1.8, and Mercury at mag -0.7, both in the constellation Cancer.
The pair will be close enough to fit within the field of view of a telescope, but will also be visible to the naked eye or through a pair of binoculars.
A graph of the angular separation between Jupiter and Mercury around the time of closest approach is available here.
The positions of the two objects at the moment of conjunction will be as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| Jupiter | 09h12m50s | 16°42'N | Cancer | -1.8 | 30"7 |
| Mercury | 09h12m50s | 16°29'N | Cancer | -0.7 | 6"5 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 17° from the Sun, which is in Leo at this time of year.

Warning
Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.

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.
