Understanding Inner and Outer Planets

The video tutorial explains the differences between inner and outer planets in the Solar System. Inner planets, including Mercury, Venus, Mars, and Earth, are rocky and dense, while outer planets like Jupiter, Saturn, Uranus, and Neptune are gaseous with lower density.
