Example:0.Is Pluto no longer a planet? Yes, It is

Is Pluto a Planet?

‘Dwarf’ is a very little star

Many people are saying that Pluto is no longer a planet. National Geographic News says that, according to the International Astronomical Union, a full planet is an object that orbits the sun and is large enough to have become round due to the force of its own gravity. Because Pluto doesn't meet these standards, the International Astronomical Union classifies Pluto as a dwarf planet. Not everyone agrees that this is a good way to decide, though. Andy Cheng, a planetary scientist at Johns Hopkins University, says that the new rules aren't clear enough and asks the question “how round is round?” “...I'll still continue to maintain that Pluto is a planet," he said.

Owen Gingerich is an astronomer and historian at Harvard University in Cambridge. He favored a special distinction for Pluto. Gingerich supported a proposal to call the big eight planets classical planets—as opposed to just plain "planets"—and Pluto and the others dwarf planets, so there would be two classes of planets. He believes that reclassifying Pluto as a dwarf planet is not "sensitive to the historical and cultural role that Pluto has played." The argument continues. What do you think it is?

1. What planet is a full planet?

2. Is Pluto the only dwarf planet?

3. How many classes of planets are according to the astronomer?
