When Ceres was discovered in 1801 it was hailed as a new planet. But then more objects were discovered hanging out in Ceres' neighborhood. All of a sudden it got demoted to a mere "minor" planet (Asteroid).
Ceres is tiny in the planetary scale, but it's the biggest asteroid by far - it accounts for 33% of all the mass in the asteroid belt, and the next largest asteroid is half its size. It's surface area is slightly larger than Texas. Take that lone star state!
Speaking of mothers, Ceres is named after the Roman goddess of agriculture, grain crops and motherly relationships. She also protects the transition of women from girlhood/unmarried to womanhood.
Her daughter is Persephone who Pluto kidnapped and took to Hades. Mother and daughter were eventually re-united, but because Persephone ate the forbidden fruit she must spend the winter in the underworld. During these months Ceres mourns, and that's why crops wither.
