Gas Giants
The Universe's Most Intense Worlds
Gas giants are massive worlds made mostly of hydrogen and helium, like Jupiter and Saturn in our Solar System. But the ones orbiting other stars can be wildly different—some scorch close to their stars, others drift alone in the void. These extreme planets teach us how massive worlds form, migrate, and survive (or get destroyed) in alien systems.
From puffy balloons inflated by heat to rogue worlds with no sun, they’re the most dramatic exoplanets we’ve found so far.
- Much larger than Earth—10–20× Earth radius common
- Extreme temperatures: some hotter than lava, others frozen
- Wild weather: winds up to 5,000 mph, glass rain, iron clouds
- Many are “puffy” from heat—lower density than cork
- Some are rogue planets—wandering without a star
- First exoplanets ever discovered were Hot Jupiters
