Earth

In the world, Human has been learning about Galaxy. Before 2006, we learned that Galaxy has nine planets, such as Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Otherwise, in 2006, Pluto was reclassified from a planet to a dwarf planet. Therefore, now, if we learn about Galaxy, it just has eight planets. The composition of planets from the Sun is still the same with before but without Pluto. The characteristics and the distance of each planet from the Sun are different. Because of that, every planet is special. Especially, Earth is the most interesting planet because it is the one of many planets that has living creatures, such as human, animals, and plants. Therefore, we will talk about Earth.
In addition, Earth stays in the fourth places from the Sun. The diameter of Earth is 7,928 miles. This makes Earth bigger than Mercury, Venus and Mars. Although Earth is bigger than some planets, but that's not made Earth is the biggest. In Galaxy, Jupiter is the biggest from the other. Earth is the one of numbers from Moons. The Earths distance from Sun is 92.9 in million of miles and the Earth revolution around Sun is about 365.26 days. Earth has two compositions, such as nitrogen and Oxygen. Therefore, Living creatures can live in the Earth. Earth has many islands. Each island has oxygen and water. Human which is live in Earth makes many stuffs that are they need and that makes Earth so different with other planets.
Actually, there are many things that we can talk about Earth. Earth is beautiful planets which is full of colors. In the Earth, we can see Sun, Moon and also Stars. In other planets, living creatures can not live because there is no oxygen and no nitrogen. As we ever heard, some smart peoples said that perhaps we can live in Mars which has nitrogen. Otherwise, Mars does not have oxygen. Therefore, as we know, people just can live in Earth. Because of that, we as a human being have to care our Earth.
