If an oort cloud object has an orbit with aphelion around 52,000 au and perihelion around 1 au, its average distance from the sun (its orbital semimajor axis) would be about half of 52,000 au. calculate that here. (1 point) use kepler's third law to figure out how long this new comet's orbital period would be. (1 point) since it takes only half an orbit to go from "out there" to "over here," figure out how long after the stars' passage it would take the disturbed oort cloud object to travel to the inner solar system. (1 point) compare that time to how long ago the stars passed through. if there were new comets created in this manner, did they already visit the inner solar system long ago, or will those comets first arrive sometime in the future? explain your answer.
