While Neptune is made of mostly hydrogen and helium, its atmosphere does include three other gases. Methane, hydrogen deuteride, and ethane make up just barely over 3 percent of the planet's atmosphere.
Neptune's minor atmospheric gases are ethane and hydrogen deuteride. Its major gases are hydrogen, helium, and methane. Neptune's blue appearance is caused by the mixture of these gases.
hydrogen and helium
The major gases in Neptune's atmosphere are hydrogen, helium, and methane. Hydrogen and helium are the most abundant gases, with methane making up a smaller but still significant proportion.
The Neptunes was created in 1990.
It not being certain of what amount or percentage is considered a "major" or "minor" gas, I have chosen to give the list of known gases in significant quantities: Hydrogen gas- 83% Helium gas- 15% Methane gas- 2%
our minor gasses in earth are helium oxygen and nitrogen
neptunes gravity is high
no one knows
The minor gases on Neptune include methane, hydrogen, helium, and trace amounts of other gases such as ammonia and water vapor. These gases contribute to Neptune's unique atmosphere and overall composition.
stop asking
Mercury's thin atmosphere is composed mostly of oxygen, sodium, hydrogen, helium, and potassium. These minor gases are present in trace amounts, with oxygen being the most abundant of the minor gases and sodium being the next most abundant. These gases play a role in the dynamics and composition of Mercury's exosphere.
Nitrogen. This is "minor".Carbon dioxide. This is the "major" gas. It makes up about 95% of the atmosphere.
