6、strations decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes.

13、f stars for a moving point of light, a planet that the observatorys founder thought existed beyond the orbit of Neptune. After years efforts, Tombaugh finally found it. Pluto was the first planet discovered by an American, and represented a moment of light in the darkness of the Great Depression. Fo

14、r decades, Pluto thrived in its role as the ninth major planet of our solar system, even though it was tiny compared to the others and so far away. However, 62 years after its discovery, two astronomers discovered another planetlike object beyond the orbit of Neptune. Six months later, they discover

15、ed a third object. It looked like Pluto might actually be a member of a sort of asteroid 【 精品教育资源文库 】 belt, similar to but way beyond one weve known about for a long time between the orbits of Mars and Jupiter.

It now shares its dwarf planet designation with three of the 1,200 bodies that have been located beyond Neptune today, collectively known as “Kuiper Belt Objects” The Kuiper Belt is populated by icy bodies that are remnants o

17、f the solar systems formation. These are the building blocks of planets. We now also know the surface of Pluto contains ices composed of methane, nitrogen, and other compounds familiar to us. It also seems to have a bright polar cap, like on Earth. Its atmosphere is very thin, but its composed large
