The interstellar medium primarily consists of hydrogen and a very small amount of helium. However, much of this interstellar hydrogen is ionized, and should be considered plasma, which is a fourth state of matter distinct from gases.
Note: The density of particles between stellar bodies is on the order of a few atoms or molecules per cubic meter. In contrast to the 1025 molecules per cubic meter found in the air on Earth, this makes space a near complete vacuum.

∙ 11y agoThe four outer gas giant planets (Jupiter, Saturn, Uranus and Neptune) are all mainly made from Hydrogen and Helium.
Jupiter's atmosphere is mainly Hydrogen (around 90%) and Helium (around 10%), while Saturn's atmosphere is around 96% Hydrogen and around 3% Helium. Both also have small amounts of Methane, Ethane and Ammonia.
Uranus' atmosphere is mainly Hydrogen (around 83%), Helium (around 15%) and Methane (around 2.3%). Neptune's atmosphere is around 80% Hydrogen and 19% Helium, with Methane making up around around 1%. The higher percentage of methane in Uranus and Neptune's atmosphere is responsible for their green and blue colouration.
