Jupiter and Saturn are the gas giants in our solar system. Uranus and Neptune are also giant planets, but NASA classifies them as ice giants because their interiors differ in composition from Jupiter’s and Saturn’s. NASA Science explains that Jupiter and Saturn are richer in hydrogen and helium.
Which planets are gas giants?
Jupiter and Saturn are the two planets NASA identifies as gas giants. They are the first two of the solar system’s four outer giant planets, in order from the Sun:
- Jupiter — gas giant
- Saturn — gas giant
- Uranus — ice giant
- Neptune — ice giant
NASA’s solar-system overview names Jupiter and Saturn as gas giants and Uranus and Neptune as ice giants.
Why aren’t Uranus and Neptune gas giants?
The distinction is about composition. NASA describes Uranus and Neptune as having interiors compositionally different from Jupiter and Saturn, which are richer in hydrogen and helium. That difference is why NASA groups Uranus and Neptune as ice giants rather than gas giants.

“Ice giant” does not mean a planet has a solid, frozen outer surface. It refers to the planets’ interior composition; Uranus and Neptune remain giant planets, just in a different category from Jupiter and Saturn.
Gas giants and ice giants compared
| Category | Planets | Composition distinction |
|---|---|---|
| Gas giants | Jupiter and Saturn | Richer in hydrogen and helium, according to NASA Science. |
| Ice giants | Uranus and Neptune | Interiors compositionally different from those of Jupiter and Saturn, according to NASA Science. |
“Giant planet” is the umbrella term for all four. Calling all four gas giants blurs the compositional distinction NASA makes between the two groups.
