CERES is a term that can be broken down into two crossword solutions: DEMETER (7 letters) and ASTEROID (8 letters). DEMETER is the Greek goddess of agriculture, grain, and fertility. She is the daughter of Cronus and Rhea and the mother of Persephone. ASTEROID is a small rocky body orbiting the sun. It is composed of rock and metal and is usually found in the ASTEROID belt between Mars and Jupiter. Together, these two solutions form the term CERES, which is the largest object in the ASTEROID belt and the only dwarf planet in the inner Solar System.
