Pluto was recently stripped of itâ€™s planet status by the IAU 9International Astronomical Union), going from a mighty planet to a lowly â€œdwarf planetâ€. The new definition of planet states that not only must it orbit the sun and be large enough to assume a nearly round shape due to gravity, but it also must â€œclear the neighborhood around its orbitâ€. Pluto was disqualified by the last restriction, as its oblong orbit overlaps Neptuneâ€™s. Many scientist were not happy about the decision though, as many of the other eight planets, including our own, do not pass the three tests with flying colors. The presence of near-Earth objects floating around means that Earth itself has not entirely cleared its orbit neighborhood. It appears that textbook writers and school teachers may make the final decision though, as what they write and teach will be what Americaâ€™s children learn.
