  • The Oort cloud of comets was formed by the ejection of icy planetesimals from the region of giant planets—Jupiter, Saturn, Uranus and Neptune—during their formation. Dynamical simulations have previously shown that comets reach the Oort cloud only after being perturbed into eccentric orbits that result in close encounters with the giant planets, which then eject them to distant orbits about 104 to 105 AU from the Sun (1 AU is the average Earth–Sun distance). All of the models constructed until… CONTINUE READING
