Conjunction of Neptune and Ceres

From the Conjunctions feed


Neptune and 1 Ceres will share the same right ascension, with Neptune passing 4°29' to the south of 1 Ceres.

From South El Monte , the pair will be visible in the dawn sky, rising at 02:28 (PDT) and reaching an altitude of 33° above the south-eastern horizon before fading from view as dawn breaks at around 05:46.

Neptune will be at mag 8.0, and 1 Ceres at mag 8.8, both in the constellation Libra.

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 Neptune 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
Neptune 15h48m40s 18°18'S Libra 8.0 2"2
1 Ceres 15h48m40s 13°48'S Libra 8.8 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 57° from the Sun, which is in Sagittarius at this time of year.
