1. After Pluto(冥王星) was found in 1930, people took it as the ninth planet in our solar system(太阳系). But it isn’t like other planets. 2.It is smaller and has an strange orbit(轨道). On August 24, scientists said, “ Pluto is not a planet.”

About 2500 scientists met in Prague. At first, some of them said that there would be 12 planets in our solar system. In the end, the scientists said that only Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune are the planets in the solar system. 3. Each of these planets has its own orbit, and each of the planets is big enough to be a planet. Pluto’s orbit overlaps(交叠) Neptune’s and it is smaller than the other planets. 4. So Pluto is classified(分类) as a dwarf(矮行星), but no longer a planet in the solar system. Students at school will have new schoolbooks to learn the new solar system.
