 IV. Reading Comprehension: Choose the best answer. 30 points."Plutoid" is the new classification that has been sanctioned for the object that was formerly known as the"ninth planet." It is nearly two years since the International Astronomical Union (IAU) stripped Pluto of itsformer status as a "proper" planet. Now an IAU committee, meeting in Oslo, has suggested that small, nearlyspherical objects orbiting beyond Neptune should carry the "plutoid" tag.As astronomy's official nomenclature organization, the IAU must approve all new names andclassifications. Its decision at the 2006 General Assembly to demote Pluto from "planet" to "dwarf planet"caused an international furor. Pluto's relegation was felt necessary because new telescope technologies hadbegun to reveal far-off objects that rivaled the world in size. Without a new classification, these discoveriesraised the prospect that textbooks could soon be talking about 50 or more "planets" in the Solar System. Thatprospect proved too much for IAU members who took the historic decision to redefine the Solar System. They1- 597 年建國後西醫 ‧ 全套詳解relegated Pluto to a grouping that includes Ceres (the largest asteroid), and Eris, an object slightly larger thanPluto that orbits even further out from the Sun in an icy region known as the Kuiper Belt.Recently the IAU further explained the plutoid definition as celestial bodies that "have sufficient mass fortheir self-gravity to overcome rigid body forces so that they assume a hydrostatic equilibrium (near-spherical)shape, and that have not cleared their orbits of debris. The two known and named plutoids are Pluto and Eris. Itis expected that more plutoids will be named as science progresses and new discoveries are made." The plutoidswill also need to have a minimum brightness. Ceres will not be considered a plutoid because of its position inthe asteroid belt between Mars and Jupiter.The classification will not placate those incensed by Pluto's demotion. Alan Stern, a former NASA spacesciences chief and principal investigator on a mission to Pluto, was scathing in his condemnation of the IAU."It's just some people in a smoke-filled room who dreamed it up," he told the Associated Press. "Plutoids orhaemorrhoids, whatever they call it. This is irrelevant."
