Matter density in interplanetary space?
I was wondering, I have heard that space is a vaccuum, but is it totally
empty in the voids between the planets? The sun jettison matter during solar flares, and there is such a thing as a solar wind. Does that mean that matter like hydrogen or helium gas might be distributed in interplanetary space? Or does the gavitational forces of the planets soak all the gas up? It might be interesting to know if gas gas/dust clouds form withing the solar system or if the stuff is even in distribution. [[Mod. note -- The interstellar medium is quite nonuniform, but a rough order-of-magnitude estimate for its density is a few atoms per cubic centimeter (most hydrogen and helium). There is also a significant amount of matter in dust grains, but I don't have specific numbers handy. -- jt]] Just curious, RustyS |
