Mars and 1 Ceres will share the same right ascension, with Mars passing 2°58' to the north of 1 Ceres.

From Ashburn (click to change), the pair will be difficult to observe as they will appear no higher than 18° above the horizon. They will become visible at around 20:26 (EDT) as the dusk sky fades, 18° above your western horizon. They will then sink towards the horizon, setting 2 hours and 26 minutes after the Sun at 22:07.

Mars will be at mag 1.5, and 1 Ceres at mag 9.0, both in the constellation Taurus.

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 Mars and 1 Ceres 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
Mars 03h24m40s +19°10' Taurus 1.5 4"0
1 Ceres 03h24m40s +16°12' Taurus 9.0 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 30° from the Sun, which is in Pisces at this time of year.
