Can a Torus be Gravitationally Bound?

[Tom MS]

Now I asked a question the other day about the gravitational binding energy of a torus, and someone responded that it cannot be gravitationally bound purely, but requires some opposing force.
Okay, fine. But, qualitatively, can a toroidal planet be gravitationally bound if it has another force holding its structure together from clumping into a ball? What do you think?

Would you call it "gravitationally bound" then? You can shoot a doughnut to space, then you have a stable torus shape in space.
For planet-sized objects, apart from artifical construction there is nothing that could support such a structure.

Right, so with artificial construction holding it together, could it still be considered gravitationally bound?

considered gravitationally bound

Those two statements do not seem consistent...
