WebIn many facilities where helium is used, it is captured and reused. If it isn't, it escapes into the air. But it doesn't simply accumulate in the atmosphere. Helium is so light that it can escape the pull of the earth's gravitational field and leave our planet forever. This is the fate of the helium in our balloons. 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 …
