Which 4 planets have an atmospheric composition of H2+He?
Yea, 2 days, no answers, after my research, Jupiter, Saturn, Uranus, and Neptune have an atmospheric composition of H2+He(Hydrogen and Helium) It just so happens that these 4 planets also are the only planets with rings, the 4 biggest planets, and the 4 planets with the most satellites (moons) Don’t rate me bad because I answered my own question please…
