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:
“Awareness has changed so that every act for children, every piece of legislation recognizes that children are part of families and that it is within families that children grow and thrive—or don’t.”
—Bernice Weissbourd (20th century)
“There is a city myth that country life was isolated and lonely; the truth is that farmers and their families then had a richer social life than they have now. They enjoyed a society organic, satisfying and whole, not mixed and thinned with the life of town, city and nation as it now is.”
—Rose Wilder Lane (1886–1965)
“Happy or unhappy, families are all mysterious. We have only to imagine how differently we would be described—and will be, after our deaths—by each of the family members who believe they know us.”
—Gloria Steinem (b. 1934)
