Oort cloud revolution period
WebStorage Clouds of Comets. From a study of the sizes and shapes of the best-determined nearly parabolic orbits, freed from the disturbing effects of the major planets, the Dutch astronomer J. Oort concluded in 1950 that fresh comets must come from a vast storage region, later called the Oort cloud, at the far outer edges of the solar system.

WebThe origin of the cloud is something that Oort (1950) speculated about. However, progress was very slow, until massive simulations of planetesimal scattering were made possible by computer developments, and the galactic tide came into the picture as a mechanism of dislodging the perihelia away from the planetary orbits. graeme bates wfiWebMass: 330,000 x Earth.
