Planets are large celestial bodies that orbit stars, including our own Sun. They come in various types, such as terrestrial planets like Earth and Mars, which have solid surfaces, and gas giants like Jupiter and Saturn, which are composed mainly of gases. Each planet has unique characteristics, including size, atmosphere, and potential for supporting life. In our solar system, there are eight recognized planets, each with its own fascinating features. For instance, Venus is known for its thick, toxic atmosphere, while Neptune is famous for its striking blue color and strong winds. Understanding planets helps us learn more about the universe and our place within it.
