Ma m\u00e1r tudjuk, hogy a Ceres \u00e1tm\u00e9r\u0151je k\u00f6r\u00fclbel\u00fcl 940 km \u2013 ez a F\u00f6ld Holdj\u00e1nak m\u00e9ret\u00e9nek k\u00f6r\u00fclbel\u00fcl egynegyede. Ugyanakkor az \u00f6sszes aszteroida teljes t\u00f6meg\u00e9nek t\u00f6bb mint egynegyed\u00e9t teszi ki.<\/p>\n<\/div>\n

Tov\u00e1bbi tizenhat aszteroida \u00e1tm\u00e9r\u0151je meghaladja a 240 km-t. Az aszteroid\u00e1k t\u00f6bbs\u00e9ge azonban csup\u00e1n n\u00e9h\u00e1ny m\u00e9ter \u00e1tm\u00e9r\u0151j\u0171 szikla \u00e9s szikladarab. Ha mindet egyetlen objektumm\u00e1 pr\u00e9seln\u00e9k \u00f6ssze, m\u00e9g \u00edgy is kisebbek lenn\u00e9nek, mint a Hold. Egyes aszteroid\u00e1k k\u00f6vesek, m\u00e1sok f\u00e9mekb\u0151l, p\u00e9ld\u00e1ul vasb\u00f3l \u00e9s nikkelb\u0151l \u00e1llnak. A legt\u00f6bbj\u00fck fekete-barna sz\u00edn\u0171 \u00e9s sz\u00e9nben gazdag.<\/p>\n

Sz\u00e1mos aszteroida csal\u00e1dokhoz tartozik. Minden csal\u00e1d azonos sz\u00edn\u0171, \u00e9s \u00fagy t\u0171nik, hogy ugyanazokb\u00f3l az anyagokb\u00f3l \u00e1ll.

Ezek k\u00f6z\u00fcl az egyik legnagyobb a Flora-csal\u00e1d, amelynek k\u00f6r\u00fclbel\u00fcl 400 ismert tagja van.<\/p>\n

Aszteroid\u00e1k a f\u0151\u00f6v\u00f6n k\u00edv\u00fcl is el\u0151fordulnak. Ezeket a Jupiter er\u0151s gravit\u00e1ci\u00f3ja vagy m\u00e1s aszteroid\u00e1kkal val\u00f3 \u00fctk\u00f6z\u00e9sek sodort\u00e1k ki eredeti p\u00e1ly\u00e1jukr\u00f3l.
