Oort cloud: Development of theory, Stellar perturbations and stellar companion hypotheses & Structure and composition

The Oort cloud (pronounced /ɔːrt/ ORT or /ʊərt/ OORT), sometimes called the Öpik–Oort cloud, is theorized to be a cloud of billions of icy planetesimals surrounding the Sun at distances ranging from 2,000 to 200,000 AU (0.03 to 3.2 light-years). Its existence was proposed in 1950 by the Dutch astronomer Jan Oort, in whose honor the idea was later named.…
