Conjunction of Mercury and Uranus

From the Conjunctions feed


Mercury and Uranus will share the same right ascension, with Mercury passing 1°15' to the north of Uranus.

From South El Monte however, the pair will not be readily observable since they will be very close to the Sun, at a separation of only 13° from it.

Mercury will be at mag -0.9, and Uranus at mag 5.6, both in the constellation Cancer.

The pair 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 Mercury and Uranus 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
Mercury 08h38m00s 20°21'N Cancer -0.9 5"2
Uranus 08h38m00s 19°06'N Cancer 5.6 3"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 13° from the Sun, which is in Gemini 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.
