1. Jupiter: The largest and most massive planet in our solar system.
2. Saturn: The second-largest and second-most massive planet.
3. Uranus: A gas giant, but significantly smaller than Jupiter and Saturn.
4. Neptune: Similar in size and mass to Uranus.
5. Earth: The largest and most massive of the terrestrial planets.
6. Venus: Slightly smaller and less massive than Earth.
7. Mars: A smaller and less massive terrestrial planet.
8. Mercury: The smallest and least massive planet in our solar system.
It's worth noting that this order is based on the planets' mass, which is different from their density.
For example, Earth is denser than Saturn even though Saturn is much more massive. This is because Saturn is primarily composed of lighter elements like hydrogen and helium.
