Cometary orbits and distributions provide empirical evidence supporting the existence of the Oort cloud
the verdict
SUPPORTED
the evidence backs this
confidence 88/100
Analyses of long-period comet orbits, semi-major axis distributions, and dynamical interactions with galactic and stellar perturbations provide robust empirical and theoretical evidence consistent with the existence of the Oort cloud.
