Families
The first collisional family—a group of objects thought to be remnants from the breakup of a single body—is the Haumea family It includes Haumea, its moons, 2002 TX300 and seven smaller bodies.† The objects not only follow similar orbits but also share similar physical characteristics. Unlike many other KBO their surface contains large amounts of ice (H2O) and no or very little tholins. The surface composition is inferred from their neutral (as opposed to red) colour and deep absorption at 1.5 and 2. μm in infrared spectrum.

—Ellen Galinsky (20th century)
“Children from humble families must be taught how to command just as other children must be taught how to obey.”
