''Orbital and Collisional Evolution of the Irregular Satellites'', The Astronomical Journal,'''126''' (2003), pages 398–429. [http://www.journals.uchicago.edu/AJ/journal/issues/v126n1/202528/202528.web.pdf (pdf)]</ref>
Based on the sizes of the satellites, the original asteroid may have been about 28 km in diameter. Since this value is near the approximate diameter of Ananke itself, it is likely the parent body was not heavily disrupted.<ref>{{
Available photometric studies add further credibility to the common origin thesis: three of the moons of the family ([[Harpalyke (moon)|Harpalyke]], [[Praxidike (moon)|Praxidike]] and [[Iocaste (moon)|Iocaste]]) display similar grey colours (average [[color index|colour indices]]: B−V = 0.77 and V−R = 0.42) while Ananke itself is on the boundary between grey and light red.<ref name=Grav2003>
