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:
“We are born into them, marry into them, even create them among the people we love. They come large and extended...or small and nuclear. But whatever their size or wherever they live, strong families give us the nurturance and strength we need in order to survive.”
—Andrea Davis (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)
“We now recognize that abuse and neglect may be as frequent in nuclear families as love, protection, and commitment are in nonnuclear families.”
