The four planets closest to the Sun are called the inner planets. They are considered terrestrial planets, meaning they are made of rock. Some of them have a thin atmosphere of gas surrounding the planet. The core is the inner part of the planet and made up mostly of metals like iron and nickel.
The four outer planets are gas giants. These planets are very far from the Sun. They don't have a hard surface that a spacecraft can land on. Instead, they are giant balls of very cold gases. Astronomers think that these planets have hot, solid cores deep beneath their atmospheres.
