The distance to Ceres varies depending on the relative positions of Earth and Ceres in our orbits. As of April 25, 2010, at 3:07 PM PDT, Ceres is at a distance of 2.158218 AU, where each AU is about 500 light-seconds. (One AU is the average distance between the Sun and the Earth.) So Ceres is currently 1079 light-seconds away. The orbit of Ceres around the Sun is an ellipse with aphelion of 2.98 AU and perihelion of 2.55 AU. When the Earth is on one side of the Sun and Ceres is on the other, our distance apart is about 3.98 AU, and when Ceres and the Earth are closest together, we are only about 1.55 AU distant. You can download the free open-source planetarium program Stellarium to see a representation of the sky and calculate the distance to any astronomical object in its database. And if you can see it, it's in there!
