Talk:Interplanetary medium

Aha! broken link here too
the link under the Heliospheric-current-sheet image has either expired or been tampered with, just as in the Sun article. There, I replaced it with what seemed to be the next best thing, this neighbour gif image, but it might not be so best at all. This field not my strong suit, so I leave it to those of you for whom it is ;) — M URGH  disc.  01:33, 28 January 2007 (UTC)

Composition and physical characteristics
"The interplanetary medium includes interplanetary dust, cosmic rays and hot plasma from the solar wind. The temperature of the interplanetary medium is approximately 100,000 K, and its density is very low at about 5 particles per cubic centimeter in the vicinity of the Earth; ... ." But what is the estimated mean density in, maybe, grams per cubic kilometre? 82.163.24.100 (talk) 19:23, 9 April 2008 (UTC)

Where did the value of 100,000 K come from? If true, this figure is confusing because no explanation is given to reconcile it with the 3 K temperature of outer space. Aniboy2000 (talk) 19:30, 5 December 2009 (UTC)

- I found the 100,000 K value on a couple of websites, but I get the impression that they copied the wikipedia article. The actual values from a slightly more respectable site can be found here: http://www.astrophysicsspectator.com/topics/milkyway/InterstellarMedium.html —Preceding unsigned comment added by 130.76.64.118 (talk) 22:40, 22 March 2011 (UTC)


 * Don't confuse Interplanetary medium and Interstellar medium. --Art Carlson (talk) 08:12, 23 March 2011 (UTC)

Clarifications needed
We have this page, Interplanetary dust cloud and Cosmic dust. These pages do not clearly explain the difference between these three concepts. Could someone please clarify this, maybe put something in the article? Should some of these pages be merged? D O N D E groovily  Talk to me  02:54, 16 September 2011 (UTC)


 * Definitely not all merged. Cosmic dust deals with dust as a generic topic. The interplanetary medium is not solely dust. As cosmic dust deals with dust in regions beyond the Solar System/interplanetary space, merging that away wouldn't be appropriate.
 * Interplanetary space, Heliosphere, and Interplanetary medium deal with the same region... but cover differing aspects of it. Not forgetting Zodiacal light and Gegenschein, also concerning the interplanetary dust cloud 76.65.129.5 (talk) 05:21, 16 September 2011 (UTC)


 * The interplanetary medium consists of interplanetary plasma and interplanetary dust. Cosmic dust is a catch-all term for both interplanetary dust and interstellar dust; there are key differences between the two. Modest Genius talk 14:53, 25 September 2011 (UTC)
