Mercury and 136199 Eris will share the same right ascension, with Mercury passing 13°58' to the north of 136199 Eris.

From Ashburn (click to change) 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 5.5 in the constellation Pisces, and 136199 Eris at mag 18.8 in the neighbouring constellation of Cetus.

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 01h43m10s +11°38' Pisces 5.5 11"8
136199 Eris 01h43m10s -02°20' Cetus 18.8 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 4° from the Sun, which is in Aries at this time of year.

Source

The circumstances of this event were computed using the DE405 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.
