Conjunction of Mercury and Pluto

From the Conjunctions feed


Mercury and 134340 Pluto will share the same right ascension, with Mercury passing 4°34' to the south of 134340 Pluto.

From Fairfield however, the pair will not be readily observable since they will be very close to the Sun, at a separation of only 15° from it.

Mercury will be at mag -0.4, and 134340 Pluto at mag 14.8, both in the constellation Sagittarius.

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 134340 Pluto 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 18h33m00s 23°53'S Sagittarius -0.4 5"0
134340 Pluto 18h33m00s 19°19'S Sagittarius 14.8 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 15° from the Sun, which is in Sagittarius 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.
