Detailed explanation-1: -The correct answer is ‘Once classified a planet cannot be redefined’. The given passage is about ‘Why Pluto is not a Planet? ‘. In 2006, Pluto, scientists told us, should no longer be called a planet, but instead a dwarf planet.
Detailed explanation-2: -Pluto was once considered the ninth planet in the solar system. It was demoted in 2006.
Detailed explanation-3: -Pluto is a complex and mysterious world with mountains, valleys, plains, craters, and maybe glaciers. Discovered in 1930, Pluto was long considered our solar system’s ninth planet. But after the discovery of similar intriguing worlds deeper in the distant Kuiper Belt, icy Pluto was reclassified as a dwarf planet.
Detailed explanation-4: -It’s smaller than any other planet–even smaller than Earth’s moon. It’s dense and rocky, like the terrestrial planets (Mercury, Venus, Earth and Mars). Pluto’s orbit is erratic. One of its moons, Charon, is about half Pluto’s size. 25-Aug-2006
