The orbits are the wrong shape

They should be ellipticals.

Um... they are?  —Preceding unsigned comment added by 68.191.79.75 (talk) 22:37, 3 April 2010 (UTC)[reply]

The math behind this plot

I am interested in the math behind this plot. There was a similar plot in a different article and the author was kind enough to provide the sourcecode. It was most useful! http://en.wikipedia.org/wiki/File:Nearby_Stars_%2814ly_Radius%29.svg

So do you determine the spatial position of a celestial body of the solar system at a certain time when you have only the ephemeris to start with? Can anybody help please? —Preceding unsigned comment added by Krystman (talk • contribs) 12:21, 19 May 2010 (UTC)[reply]
