Venus and 1 Ceres will share the same right ascension, with Venus passing 1°54' to the north of 1 Ceres.

From Cambridge, the pair will be difficult to observe as they will appear no higher than 9° above the horizon. They will become visible around 16:33 (EDT) as the dusk sky fades, 9° above your south-western horizon. They will then sink towards the horizon, setting 1 hour and 35 minutes after the Sun at 17:47.

Venus will be at mag -3.9, and 1 Ceres at mag 9.2, both in the constellation Sagittarius.

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 Venus 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
Venus 18h24m50s -24°46' Sagittarius -3.9 11"5
1 Ceres 18h24m50s -26°41' Sagittarius 9.2 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 27° from the Sun, which is in Ophiuchus at this time of year.

The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
