An asteroid family is a population of asteroids that share similar proper orbital elements, such as semimajor axis, eccentricity, and orbital inclination. The members of the families are thought to be fragments of past asteroid collisions. An asteroid family is a more specific term than asteroid group whose members, while sharing some broad orbital characteristics, may be otherwise unrelated to each other.

Famous quotes containing the word family:
“For most women who are considering it, single motherhood is not their first choice, but it’s not their last one either. They would prefer a husband in their family, but they’d rather have a family without one than no family at all.”
—Anne Cassidy. “Every Child Should Have a Father But....,” McCall’s (March 1985)
