--All other star groups visible to the naked eye are unbound, with the possible exception of the Hyades. Pleiades and Orion as gravitationally bound star groups.
Are you sure about this?
As far as I know, Orion is composed of several different stellar objects, including 2 open clusters (NGC1662 & NGC 1663) and 3 nebulae (M42, M43 and M78) none of which have ever been close enough to interact with each other.
What is your source for this claim?
