What's surprising is that the dominate theories of ring formation don't really allow for something this small to form rings. Too small for tidal forces. Weak gravity would mean it's hard to hold the products of a collision. If the asteroid has shepherd satellites, they would be even weaker.
At least, that's why I'm surprised.
