Conjunction of Uranus and Ceres

From the Conjunctions feed


Uranus and 1 Ceres will share the same right ascension, with Uranus passing 2°38' to the north of 1 Ceres.

From South El Monte , the pair will be visible between 21:30 and 01:57. They will become accessible at around 21:30, when they rise to an altitude of 21° above your south-eastern horizon. They will reach their highest point in the sky at 23:43, 29° above your southern horizon. They will become inaccessible at around 01:57 when they sink below 21° above your south-western horizon.

Uranus will be at mag 5.5, and 1 Ceres at mag 7.5, both in the constellation Ophiuchus.

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 Uranus 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
Uranus 17h34m50s 23°28'S Ophiuchus 5.5 3"8
1 Ceres 17h34m50s 26°06'S Ophiuchus 7.5 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 163° from the Sun, which is in Gemini at this time of year.
