Quizplus · Accepted Answer

Long period comets are believed to originate from the Oort Cloud, a hypothetical spherical cloud of icy objects surrounding our solar system at a distance of about 50,000 astronomical units (AU) from the Sun. The Oort Cloud is thought to contain billions of comets, which can be perturbed by the gravity of passing stars and occasionally sent into the inner solar system, where they become visible as long period comets. Long period comets are thought to originate from the outer edges of our solar system in a region called the Oort Cloud, which contains trillions of icy objects. These comets have highly elliptical orbits that can take them far away from the Sun and then back in towards the inner solar system. The other choices (A, B, C, E) are not where long period comets are primarily thought to come from.
