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.

Famous quotes containing the word families:
“Being dismantled before our eyes are not just individual programs that politicians cite as too expensive but the whole idea that society has a stake in the well-being of children down the block and the security of families on the other side of town. Whether or not kids eat well, are nurtured and have a roof over their heads is not just a consequence of how their parents behave. It is also a responsibility of society—but now apparently a diminishing one.”
—Richard B. Stolley (20th century)
“Families need families. Parents need to be parented. Grandparents, aunts, and uncles are back in fashion because they are necessary. Stresses on many families are out of proportion to anything two parents can handle.”
—T. Berry Brazelton (20th century)
“Children from humble families must be taught how to command just as other children must be taught how to obey.”
—Friedrich Nietzsche (1844–1900)
