Answer for screen readers
The inner planets are Mercury, Venus, Earth, and Mars. These planets are closer to the Sun and are rocky. The outer planets are Jupiter, Saturn, Uranus, and Neptune, which are further from the Sun and primarily composed of gas.
More Information
Inner planets are rocky and are the closest to the Sun, making them terrestrial planets. Outer planets, being further away, are much larger in size and mostly made of gases, giving them the moniker 'gas giants'.
Tips
Don't confuse the order of planets. The inner planets are always closer to the Sun, and their characteristics differ significantly from the gaseous outer planets.
