Let $\Delta$ be the optimal packing density of $\mathbb R^n$ by unit balls.We show the optimal packing density using two sizes of balls approaches $\Delta+ (1 - \Delta) \Delta$ as the ratio of the radii tends to infinity. Moregenerally, if $B$ is a body and $D$ is a finite set of bodies, then the optimaldensity $\Delta_{\{rB\} \cup D}$ of packings consisting of congruent copies ofthe bodies from $\{rB\} \cup D$ converges to $\Delta_D + (1 - \Delta_D)\Delta_{\{B\}}$ as $r$ tends to zero.

Optimal densities of packings consisting of highly unequal objects
