Web2 Answers Sorted by: 23 They are very sparse. Typical densities are in the range of 100 to 10,000 particles per cm 3. This is much more dense than the general interstellar medium (1 particle per cm 3 ), but much, much less dense than anything you are used to - air is around 10 19 particles per cm 3. WebStars are fueled by the nuclear fusion of hydrogen to form helium deep in their interiors. The outflow of energy from the central regions of the star provides the pressure necessary to keep the star from collapsing under its own weight, and the energy by which it shines.
