💡 Analogies

If the inner planets are houses on a street, the outer planets are entire cities — Jupiter alone has more mass than everything else in the solar system combined (excluding the Sun).

⚠️ Common Misconceptions

Myth: You could land on Jupiter or Saturn.

Reality: Gas giants have no solid surface to land on. As you descended, the gas would simply get denser and hotter, eventually transitioning to liquid metallic hydrogen. There's no clear boundary — just an increasingly crushing ocean of gas.
