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:
“Whatever else American thinkers do, they psychologize, often brilliantly. The trouble is that psychology only takes us so far. The new interest in families has its merits, but it will have done us all a disservice if it turns us away from public issues to private matters. A vision of things that has no room for the inner life is bankrupt, but a psychology without social analysis or politics is both powerless and very lonely.”
—Joseph Featherstone (20th century)
“Notwithstanding the unaccountable apathy with which of late years the Indians have been sometimes abandoned to their enemies, it is not to be doubted that it is the good pleasure and the understanding of all humane persons in the Republic, of the men and the matrons sitting in the thriving independent families all over the land, that they shall be duly cared for; that they shall taste justice and love from all to whom we have delegated the office of dealing with them.”
—Ralph Waldo Emerson (1803–1882)
“Children from humble families must be taught how to command just as other children must be taught how to obey.”
—Friedrich Nietzsche (1844–1900)
