Physics, Astronomy & Cosmology / Is a stable axial tilt of a planet possible without a moon?

I am interested if stable axial tilt of planet is aways caused by moons or it may happen without moon. Like that the planet has stable Axial tilt because it had a good kick at start or something like that. I know our planet would be more unstable without moon and other stable planets mostly have some moons too. So is stable Axial tilt always caused by moons or it may be stabilized some other way, lets say some other objects may stabilize it or it just happened to be stabilized since ever.. or maybe it during the very long time of existing somehow stabilized it self? Thank you
