1 Ceres and 136199 Eris will share the same right ascension, with 1 Ceres passing 2°57' to the north of 136199 Eris.

From Fairfield however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 15° above the horizon at dawn.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

1 Ceres will be at mag 9.2, and 136199 Eris at mag 18.9, both in the constellation Cetus.

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 1 Ceres 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
1 Ceres 01h44m40s +00°29' Cetus 9.2 0"0
136199 Eris 01h44m40s -02°27' Cetus 18.9 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 70° from the Sun, which is in Gemini at this time of year.
