   Density and Pressure
   Despite its high temperature, the corona/ is extremely tenuous. The density drops off rapidly with altitude. At the Sun's/ visible surface (the photosphere/ line), the density is approximately $10^{18}$ particles per cubic centimeter, decreasing to about $10^8$ particles per cubic centimeter at one solar radius/ above the surface [4]. The pressure/ in the corona/ is significantly lower than [Earth's atmospheric pressure](/entries/earth-s-a…
