WebAug 17, 2024 · There isn’t much helium on planet Earth, however; just a few parts per million. The problem is that the helium nucleus is so light that our Earth’s gravity cannot hold it. Once helium enters our atmosphere, it escapes into the vacuum of space, lost from Earth, swept along with the solar wind. WebThe smaller the object, the lower the gravity, so the escape velocity is lower and it is harder to retain an atmosphere (Moon and Mercury). Finally, you can lose atmosphere to the surface. The atmosphere can condense onto the surface (rain and snow). On Earth, much of the carbon dioxide that is normally generated is dissolved into the oceans. 2.
