Question
In 1986, the distance of closest approach of Halley’s comet to the Sun is 0.57AU. (1 AU is the mean Earth-Sun distance = 150 million kilometers.) The comet’s speed at closest approach is
54.97 km/s.
(a) – By 1989, Halley’s comet had traveled to a distance corresponding to the orbit of Saturn at 9.56AU. What was the speed of Halley’s Comet at that time? Give your answer in units of km/s.
(b) – In 2024, Halley’s comet will be at the furthest distance from the sun corresponding to about 35AU. What will the speed of Halley’s Comet be at that time?
54.97 km/s.
