ones in the asteroid belt. For a complete list, see . Eos family The Eos family (adj. Eoan; 9,789 members, named after 221 Eos) Eunomia family The Eunomia family (adj. Eunomian; 5,670 known members, named after 15 Eunomia) is a family of S-type asteroids. 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. Flora family The Flora family (adj. Florian; 13,786 members, named after 8 Flora) is the 3rd-largest family. Broad in extent, it has no clear boundary and gradually fades into the surrounding background population. Several distinct groupings within the family, possibly created by later, secondary collisions. It has also been described as an asteroid clan. Hungaria family The Hungaria family (adj. Hungarian; 2,965 members, named after 434 Hungaria) Hygiea family The Hygiea family (adj. Hygiean; 4,854 members, named after 10 Hygiea) Koronis family The Koronis family (adj. Koronian; 5,949 members, named after 158 Koronis) Nysa family The Nysa family (adj. Nysian; 19,073 members, named after 44 Nysa). Alternatively named Hertha family after 135 Hertha. Themis family The Themis family (adj. Themistian; 4,782 members, named after 24 Themis) Vesta family The Vesta family (adj. Vestian; 15,252 members, named after 4 Vesta) All families In 2015, a study identified 122 notable families with a total of approximately 100,000 member asteroids, based on the entire catalog of numbered minor planets, which consisted of almost 400,000 numbered bodies at the time (see catalog index for a current listing of numbered minor planets). The data has been made available at the "Small Bodies Data Ferret". The first column of this table contains the family identification number or family identifier number (FIN), which is an attempt for a numerical labeling of identified families, independent of their currently used name, as a family's name may change with refined observations, leading to multiple names used in literature and to subsequent confusion. Other families or dynamical groups Other asteroid families from miscellaneous sources (not listed in the above table), as well as non-asteroid families include: See also Proper orbital elements :Category:Asteroid groups and families Notes References Further reading Bendjoya, Philippe; and Zappalà, Vincenzo; "Asteroid Family Identification", in Asteroids III, pp. 613–618, University of Arizona Press (2002), V.
