Ceres at Opposition

   Monday June 29th Dwarf Planet Ceres reaches opposition. This places the Earth in between Ceres and the Sun, much like the arrangement of the Sun, Earth, and Moon during full Moon phase. When at opposition an outer planet is visible for most if not all of the night hours as it rises around sunset and then sets around sunrise.

   Ceres, at 7th magnitude, is currently within the boundaries of the constellation Capricornus the Sea Goat and is about 1o west from 4th magnitude Omega Capricorni. Ceres is bright enough to see with binoculars and regular observing will show Ceres moving away from Omega Capricorni.

   Learn more about Dwarf Planet Ceres by visiting the NASA Dawn mission web site where we have the Dawn spacecraft orbiting Ceres.


Caution: Objects viewed with an optical aid are further than they appear.

  1. Great post. And we’re only at the beginning of the learning curve we’ll get from Dawn. Very exciting times indeed for our understanding of Ceres and, I think, for the solar system as a whole.
