It is the most prominent family in the intermediate asteroid belt and the 6th-largest family with approximately 1.4% of all main belt asteroids. [3]: 23 Flora family The Flora family (adj. Florian; 13,786 members, named after 8 Flora) is the 3rd-largest family.
The asteroid belt is a torus-shaped region in the Solar System, ... Approximately one-third of the asteroids in the asteroid belt are members of an asteroid family.
The Flora family (adj. Florian; FIN: 402; also known as the Ariadne family) is a prominent family of stony asteroids located in the inner region of the asteroid belt. It is one of the largest families with more than 13,000 known members, or approximately 3.5% of all main-belt asteroids .
The Themis family (adj. Themistian; FIN: 602) is a family of carbonaceous asteroids located in the outer portion of the asteroid belt, at a mean distance of 3.13 AU from the Sun. It is one of the largest families with over 4700 known members, [1] and consists of a well-defined core of larger bodies surrounded by a region of smaller ones.
The 4:1 resonance Kirkwood gap (at 2.06 AU) marks the outer boundary of the Hungaria family, while interactions with Mars determine the inner boundary. For comparison the majority of asteroids are in core region of the asteroid belt, which lies between the 4:1 gap (at 2.06 AU) and the 2:1 gap (at 3.27 AU). [citation needed]
The Baptistina family (FIN: 403) is an asteroid family of more than 2500 members that was probably produced by the breakup of an asteroid 170 km (110 mi) across 80 million years ago following an impact with a smaller body. The two largest presumed remnants of the parent asteroid are main-belt asteroids 298 Baptistina and 1696 Nurmela.
The Eos family (adj. Eoan / iː ˈ oʊ ə n /; FIN: 606) is a very large asteroid family located in the outer region of the asteroid belt. This family of K-type asteroids is believed to have formed as a result of an ancient catastrophic collision. The family's parent body is the asteroid 221 Eos.
The Massalia family (adj. Massalian; FIN: 404) is a family of asteroids in the inner asteroid belt, named after its parent body, 20 Massalia. It consists of S-type asteroids with very low inclinations, straddling the 1:2 resonances with Mars. There are more than 6,000 known Massalian asteroids. [1]
