The reason why Titan has a thick atmosphere while its Jovian clones Ganymede and Callisto have nothing is addressed. It is argued that this contrast is a predictable consequence of impact erosion, i.e., the escape of atmospheric gases as a consequence of hypervelocity impact, the average impact velocity of stray bodies on Titan being lower than on Ganymede and Callisto. A model to examine this hypothesis is presented.
