Conjunction of Mars and Ceres

From the Conjunctions feed


Mars and 1 Ceres will share the same right ascension, with Mars passing 1°25' to the north of 1 Ceres.

From Fairfield , the pair will be visible in the dawn sky, rising at 02:07 (EST) – 3 hours and 46 minutes before the Sun – and reaching an altitude of 26° above the eastern horizon before fading from view as dawn breaks at around 04:39.

Mars will be at mag 1.3 in the constellation Taurus, and 1 Ceres at mag 9.0 in the neighbouring constellation of Orion.

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 05h53m40s 23°38'N Taurus 1.3 4"7
1 Ceres 05h53m40s 22°12'N Orion 9.0 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 48° from the Sun, which is in Cancer at this time of year.
