Hoy en d\u00eda se sabe que Ceres tiene una anchura de unos 940 km, lo que equivale aproximadamente a una cuarta parte del tama\u00f1o de la Luna de la Tierra. Sin embargo, representa m\u00e1s de una cuarta parte del peso total de todos los asteroides.<\/p>\n<\/div>\n

Otros diecis\u00e9is asteroides tienen m\u00e1s de 240 km. de tama\u00f1o. Sin embargo, la mayor\u00eda son rocas y pe\u00f1ascos de apenas unos cuantos metros de tama\u00f1o. Si todos ellos se pudieran reunir para formar un solo objeto, todav\u00eda ser\u00edan m\u00e1s peque\u00f1os que la Luna. Algunos asteroides son pedregosos, mientras otros est\u00e1n formados por metales como hierro y n\u00edquel. En su mayor\u00eda, tienen un color marr\u00f3n oscuro y son ricos en carbono.<\/p>\n

Muchos asteroides pertenecen a familias. Cada familia tiene asteroides del mismo color y parece estar formada por los mismos materiales. Los asteroides de cada familia se desplazan juntos en diferentes partes del cintur\u00f3n principal. Una de las familias m\u00e1s numerosas es Flora, con unos 400 miembros conocidos.<\/p>\n

Tambi\u00e9n es posible encontrar asteroides fuera del cintur\u00f3n principal, ya que la fuerte gravedad de J\u00fapiter o las colisiones con otros asteroides los han lanzado fuera de su hogar. Algunos se han convertido en lunas del planeta gigante. Cientos de miles de asteroides, algunos de ellos de gran tama\u00f1o, pasan cerca de la Tierra.<\/p>","protected":false},"excerpt":{"rendered":"
