Web1 okt. 2024 · We know Halley's Comet returns every 75-76 years. We can reasonably compute its elliptical orbit. We know that the Oort Cloud is a cloud of predominantly icy planetesimals proposed to surround the Sun at distances ranging from 2,000 to 200,000 au. We divide it into two regions: a disc-shaped inner Oort cloud (or Hills cloud) and a … WebThe perihelion of Halley’s comet is 0.586 AU and the aphelion is 17.8 AU. Given that its speed at perihelion is 55 km/s, what is the speed at aphelion ( 1 AU = 1.496 × 10 11 m )? ( Hint: You may use either conservation of energy or angular momentum, but the latter is much easier.) 51. great house in sonning
