What is the atmospheric composition of Saturn?

Answer 1

Atmospheric composition (by volume, uncertainty in parentheses) of Saturn

Major:

Hydrogen (H2) - 96.3% (2.4%);

Helium (He) - 3.25% (2.4%)

Minor (ppm):

Methane (CH4) - 4500 (2000);

Ammonia (NH3) - 125 (75);

Hydrogen Deuteride (HD) - 110 (58);

Ethane (C2H6) - 7 (1.5)

Aerosols: Ammonia ice, water ice, ammonia hydrosulfide

Answer 2

The atmospheric composition of Saturn is primarily comprised of hydrogen and helium. There are small amounts of methane and ammonia in its atmosphere as well.

Answer 3

Saturn's atmosphere is primarily composed of hydrogen and helium, with trace amounts of methane, ammonia, and water vapor. The presence of these gases gives Saturn its distinct yellowish color.
