  We show that the existence of prograde equatorial satellites is consistent
with a collisional tilting scenario for Uranus. In fact, if the planet was
surrounded by a proto-satellite disk at the time of the tilting and a massive
ring of material was temporarily placed inside the Roche radius of the planet
by the collision, the proto-satellite disk would have started to precess
incoherently around the equator of the planet, up to a distance greater than
that of Oberon. Collisional damping would then have collapsed it into a thin
equatorial disk, from which the satellites eventually formed. The fact that the
orbits of the satellites are prograde requires Uranus to have had a
non-negligible initial obliquity (comparable to that of Neptune) before it was
finally tilted to 98 degrees.
