As we knew, our solar system has all nine planets. The sun is the center, and the other planets revolve it. But today, scientists found that there are ten planets in our solar system. This is a interesting thing that it is the reason that scientists who research in space have to rewrite text books about astronaut. For a long time researching and observing the space, Micheal Brown discovered a new and unusual planet, a tenth planet with a bright light. He didn’t know what to call it, and then he discussed with his fellows and decided to call it Zena as name of a female character in old Greek stories. He informed that every day astrologists find out hundreds of new planets. Therefore, they have a large account of planets, and their object is to identify them. It is so hard to discover solar system because it has billions of planets and those planets are right in order. They can change anytime that they can not know. They also need to identify which one is planet, and which is unplanet. So, exploring and naming a new planet have to be accepted by experts. There are many ideas that show displeasures for planets that are not recognize as a planet of solar system. Our universe is very wide and open and has many other planet systems and we can not know exactly how many planets are existing at all. However, discovering the tenth planet is a new advance in our age that may help us to find out more mysteries about our broad universe.
