On the moment of inertia of planar convex regions and possible special nature of circular disks

We consider uniform convex planar regions and lines through their center of mass; the latter are parametrized by an angle $\alpha$ it makes with some reference direction.

Are there uniform convex planar regions other than the circular disk with the property: the region has equal moment of inertia about every line through the center of mass lying within a finite range of values of $\alpha$?

And what could be said about other moments?
