Our moon is huge for a planet of Earth's size, but not compared to the big moons of Jupiter and Saturn.

Last time I looked it up, I used Pluto's moons as a reference because some of them are smaller than DS1, but Charon is quite a bit bigger. Based on the shapes of Pluto's moons, I think even if DS1 were solid it would still be too small to compact itself into a sphere with its own gravity.

Fun fact: Charon is even more huge relative to Pluto (just over 50% of Pluto's diameter) than Luna is compared to Earth (about 25% of Earth's diameter).

fun fact, pluto and charon are technically a binary planet(oid), because the point they orbit is in-between them. (Charon doesn't orbit Pluto, they both circle empty space)

Pluto has more than one satellite?
