Here's a more detailed breakdown:
* Hydrogen (H2): Makes up about 89% of Jupiter's atmosphere by mass.
* Helium (He): Makes up about 10% of Jupiter's atmosphere by mass.
* Trace Gases: The remaining 1% is composed of trace gases like methane (CH4), ammonia (NH3), water (H2O), and traces of hydrocarbons.
These trace gases are important because they absorb sunlight at specific wavelengths, giving Jupiter its distinctive colorful bands.
It's important to note that Jupiter's atmosphere is very dynamic, with powerful winds, swirling storms, and a complex circulation system. This makes it a fascinating object to study for scientists.
