Mercury and 134340 Pluto will share the same right ascension, with Mercury passing 7°02' to the south of 134340 Pluto.
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 16° from it.
Mercury will be at mag -0.6, and 134340 Pluto at mag 15.0, both in the constellation Leo.
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 | 09h34m00s | 16°00'N | Leo | -0.6 | 5"3 |
| 134340 Pluto | 09h34m00s | 23°02'N | Leo | 15.0 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 16° from the Sun, which is in Cancer at this time of year.
