or more. The interesting point is that although the density of these objects is very high, the particles do not have any compression. In fact, if it were possible to build a spacecraft that could land on the surface of a proton star, it would be possible to extract protons from its surface using a spoon. In fact, it can be said that such density is part of their natural structure and nature, and the term compression that we have in mind cannot be attributed to them. To better understand this, consider mercury, which is a high-density element but is a liquid metal and can be easily separated (Mercury has a higher density than iron).
