Mercury and 136199 Eris will share the same right ascension, with Mercury passing 6°28' to the north of 136199 Eris.
From Fairfield however, the pair will not be readily observable since they will be very close to the Sun, at a separation of only 17° from it.
Mercury will be at mag -0.9, and 136199 Eris at mag 18.6, both in the constellation Pisces.
A graph of the angular separation between Mercury and 136199 Eris 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 | 01h57m00s | 10°08'N | Pisces | -0.9 | 5"3 |
| 136199 Eris | 01h57m00s | 3°40'N | Pisces | 18.6 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 13° from the Sun, which is in Aries at this time of year.
