One theory of its formation proposed by Higuchi and Mukai invoke the Kozai mechanism's alternating increases of inclination of eccentricity.
One theory of its formation proposed by Higuchi and Mukai invoke the Kozai mechanism's alternating increases of inclination of eccentricity. Another theory, that it formed from a large protostar nebula, was proposed by Safronov and Cameron and support for it includes the two peaks from a histogram plot of the aphelia of its long-period objects. First proposed by Ernest Opik, it is the place of origin of Hyakutake and Hale-Bopp. For 10 points, identify this region beyond Uranus and Neptune from which long-term comets originate.
