Two questions come to mind:
- Presumably i is the inclination difference between the perturbed and larger bodies?
- The value of 3 is used to distinguish asteroids from certain comets, but how is the distinguishing done? Do the comets have parameter less than or more than 3?

Yes for the inclination; please bear with this stub, I needed it for TNO and hope to extend it in the near future... Yes, 'most' comets have the parameter between 2 and 3. Deuar, could you please help me with the article's title? Initially, without realising, I used some strange code for the apostrophe. Then I panicked and moved it to standard ' but the link in Tisserand's Criterion is not working. Could you please have a look and fix it? Thank you!Eurocommuter 18:36, 17 July 2006 (UTC)
- Hi Eurocommuter! :-) Thanks. This name thing is pretty pecuiliar. No fix yet, but i'm still looking into it... Deuar 19:26, 17 July 2006 (UTC) Got it! those bugs can be pretty sneaky... Deuar 19:33, 17 July 2006 (UTC)
Why the link?[edit]
The link to "David Jewitt page" in "External Links" is obscure. This page doesn't seem to elucidate the subject; I'd suggest it be dropped.
- I suppose you clicked on 'page' and not on David Jewitt? But I have to agree. Internet resources appear rare. I’m extending slowly the articles on 3-body problem simple, useful results (Jacobi integral, Tisserand's relation, necessary for TNO and irregulars satellites in particular. But the critical mass is not there, yet. Eurocommuter 17:33, 12 September 2006 (UTC)
Merge ?[edit]
Shouldn't this article be merged with Tisserand's relation which extensively explains the origin of the parameter?
Besides, why does the formula use here and merely there? Either expression must be wrong. Or it's late, i'm tired, and i don't know what i'm saying? MinnieRae (talk) 02:16, 17 April 2008 (UTC)
