Haumea (pronounced how-MAY-ah), the third-largest known dwarf planet in the Kuiper belt (at the time of discovery) was discovered on Dec 28, 2004 by Mike Brown; et.al. of CalTech using the Keck Observatory in Hawaii...
What's in a Name
In Mike Brown's words: "The name (Haumea) was chosen by David Rabinowitz of Yale University, one of the co-discoverers of Santa (along with me and Chad Trujillo of Gemini Observatory in Hawaii). He chose the name because the name Haumea is closely associated with stone, and Santa (as we knew it at the time) appeared to be made of nothing but rock."...
And to quote: "Haumea is the goddess of childbirth and fertility in Hawaiian mythology. Her many children sprang from different parts of her body. She takes many different forms and has experienced many different rebirths. As the goddess of the earth, she represents the element of stone."
