The discovery of Eris
A Was not surprising, because the existence of a massive "Planet X" had been predicted nearly a century ago.
B
Was surprising, due to its "backwards" orbit around the Sun.
C Was surprising, since we thought we knew about all large objects in the solar system.
Was not surprising, because other Kuiper belt objects approaching the size of Pluto had already been discovered.

In August of 2006, leading astronomers established new guidelines and declared that Pluto is no longer a planet. Which of the following is either false or least consistent with the new guidelines? Group of answer choices Pluto is by far the largest known object in the Kuiper belt, while Eris is the largest known object in the asteroid belt. A planet must have cleared the neighborhood around its orbit. Pluto is automatically disqualified from being a planet because its oblong orbit overlaps with Neptune's. A planet must have sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a nearly round shape. Pluto and the asteroid Ceres are both now classified as dwarf planets.arrow_forward
