Conjunction of Jupiter and Mercury

From the Conjunctions feed


Jupiter and Mercury will share the same right ascension, with Jupiter passing 40' to the south of Mercury.

From South El Monte , the pair will be difficult to observe as they will appear no higher than 8° above the horizon. They will be visible in the dawn sky, rising at 05:22 (PDT) – 1 hour and 2 minutes before the Sun – and reaching an altitude of 8° above the eastern horizon before fading from view as dawn breaks at around 06:08.

Jupiter will be at mag -1.7, and Mercury at mag -1.2, both in the constellation Leo.

The pair 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 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 09h46m20s 14°11'N Leo -1.7 30"4
Mercury 09h46m20s 14°51'N Leo -1.2 5"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 12° 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.
