I'm teaching some physics now and I wanted the figure for the atomic density of interplanetary space in atoms/cubic cm so that I can make it clear to my students why there is no friction in space to slow down planets or spaceships. I've spent way too much time unsuccessfully surfing the web for this statistic, and I thought maybe someone on this list may have a reference book which has it. Clearly, my web searching skills need some work! David Glaser Willard M.S.
