Hi there!

The matter of how the data for physical characteristics in the numbered asteroid pages (E.g. on List of asteroids) is obtained has been bugging me for some time. For example, the mean temperature. I haven't been able to find any particular place where such matters have been explained or references given. I suppose that I might not be the only one who wonders about this.

So - i've tried to put up what I surmise so far, as a bait for all those of you who have been working with the asteroids for longer, and know what is up. Edit please! Deuar 20:55, 7 December 2005 (UTC)

Should this article be moved out from the article namespace since it doesn't seem to be a real encyclopedic article but more like a guide page?--JyriL talk 22:07, 8 January 2007 (UTC)
That sounds spot on, as long as it remains editable. The point of it is basically to be a very long footnote to Template:Infobox_Minor_Planet. I'd do it myslelf, but i'm not familiar with how to carry it out. Deuar 11:38, 9 January 2007 (UTC)

\frac{GM}{r_{max}^2} for the surface gravity was wrong. The formula is only true for spherically symmetric bodies (see shell theorem). Maybe it's good enough as an approximation (the same applies to the escape velocity, and also to the mean temperature), but the wording (before my edit) seemed to indicate that it's an exact formula.
