An asteroid is a minor planet—an object that is neither a true planet nor a comet—that orbits within the inner Solar System. They are rocky, metallic, or icy bodies with no atmosphere. The size and shape of asteroids vary significantly, ranging from small rubble piles under a kilometer across to Ceres, a dwarf planet almost 1000 km in diameter.
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.

284996 Rosaparks, provisional designation 2010 LD58, is a dark background asteroid from the outer regions of the asteroid belt, approximately 3.5 kilometers (2.2 miles) in diameter. It was discovered on 9 June 2010 by scientists working with data from the Wide-field Infrared Survey Explorer spacecraft. [1]
Una familia de asteroides es una población de asteroides con un origen común que comparten elementos orbitales similares como el semieje mayor, la excentricidad o la inclinación de la órbita. Se cree que los miembros de las familias son fragmentos de colisiones de asteroides.
