  According to adaptive-optics observations by Ferrais et al., (22) Kalliope is
a 150-km, dense and differentiated body. Here, we interpret (22) Kalliope in
the context of bodies in its surroundings. While there is a known moon Linus,
with a 5:1 size ratio, no family has been reported in the literature, which is
in contradiction with the existence of the moon. Using the hierarchical
clustering method (HCM) along with physical data, we identified the Kalliope
family. Previously, it was associated to (7481) San Marcello. We then used
various models (N-body, Monte-Carlo, SPH) of its orbital and collisional
evolution, including the break-up of the parent body, to estimate the dynamical
age of the family and address its link to Linus. The best-fit age is (900+-100)
My according to our collisional model, in agreement with the position of (22)
Kalliope, which was modified by chaotic diffusion due to 4-1-1 three-body
resonance with Jupiter and Saturn. It seems possible to create Linus and the
Kalliope family at the same time, although our SPH simulations show a variety
of outcomes, for both satellite size and the family size-frequency
distribution. The shape of (22) Kalliope itself was most likely affected by
gravitational reaccumulation of `streams', which creates characteristic hills
observed on the surface. If the body was differentiated, its internal structure
is surely asymmetric.
