  Recently it was found from Cassini data that the mean recession speed of
Titan from Saturn is $v=11.3\pm 2.0$ cm/yr which corresponds to a tidal quality
factor of Saturn $Q\cong 100$ while the standard estimate yields $Q\ge 6\cdot
10^4$. It was assumed that such a large speed $v$ is due to a resonance locking
mechanism of five inner mid-sized moons of Saturn. In this paper, we show that
an essential part of $v$ may come from a local Hubble expansion, where the
Hubble-Lema\^{\i}tre constant $H_0$ recalculated to the Saturn-Titan distance
$D$ is 8.15 cm/(yr $D$). Our hypothesis is based on many other observations
showing a slight expansion of the Solar system and also of our Galaxy at a rate
comparable with $H_0$. We demonstrate that the large disproportion in
estimating the $Q$ factor can be just caused by the local expansion effect.
