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.

“The brotherhood of men does not imply their equality. Families have their fools and their men of genius, their black sheep and their saints, their worldly successes and their worldly failures. A man should treat his brothers lovingly and with justice, according to the deserts of each. But the deserts of every brother are not the same.”
—Aldous Huxley (1894–1963)
“The authoritarian child-rearing style so often found in working-class families stems in part from the fact that parents see around them so many young people whose lives are touched by the pain and delinquency that so often accompanies a life of poverty. Therefore, these parents live in fear for their children’s future—fear that they’ll lose control, that the children will wind up on the streets or, worse yet, in jail.”
—Lillian Breslow Rubin (20th century)
