This week on Looking Up we learn about Ceres, an object first thought to be a planet, then designated an asteroid, and now considered to be a dwarf planet.
Can I be Ceres for a moment? I want to talk to you about the planet, I mean asteroid, I mean dwarf planet, visible in southern Colorado skies right now. In 1801, a Sicilian astronomer went looking for what was thought to be a missing planet between Mars and Jupiter. And there he found the object we today call Ceres.
