hi steemit nice to meet you guys, I want to explain about the solar system, it can be said this is useful.
Earth is the third planet of the sun which is the largest and fifth largest planet of the planet's delta in the solar system. Earth is also the largest planet of the four planets of the Earth's solar system. the earth is sometimes called the world or the blue planet. the earth formed about 4.54 billion years ago. More than 70% of the earth's surface is covered with water, and the remainder consists of continents and island islands that have many lakes and other water sources that contribute to the formation of hydrosphere. when it encircles the sun in one orbit, the earth rotates on its axis of 366.26 times, which creates 365, 26 days of sun or a cideris year. the moon is the only natural satellite of the earth, which began orbiting the earth about 4.53 billion years ago ... the earth is home to millions of living things, including humans. human-inhabited areas of the world are grouped into 200 sovereign states, which interact with each other through diplomacy, travel, trade and military action.
