wanted: HD 209458 - planet b - Sun alignment

Post #1by Zimriel » 06.12.2002, 07:36

56086.5 Gregorian days before 6:19 AM GMT on 15 November 1999, roughly, the innermost planet of HD 209458 passed between that star and ours.

Unfortunately when I set out from Earth to HD 209458, the inclination of the ecliptic (at least that planet in it) had it such that the planet never crossed the star.

Any plans to alter stellar data such that it includes an optional ecliptic angle to the Sun?

Specifically, HD 209458's i=85.2 degrees, and relative to that:

Code: Select all

"b" "HD 209458"
{
   Texture "gasgiant.jpg"
   Mass      220
   Radius    101000
   Albedo    .1

   # orbital data
   EllipticalOrbit {
      Period          0.0096502
      SemiMajorAxis   0.045
      Eccentricity    0.0
      Epoch           2395458
      AscendingNode   ?
      LongOfPericenter ?
      MeanLongitude    ?
   }
}


Low albedo in accordance with http://groups.google.com/groups?q=%22HD ... edu&rnum=2

This is something that I plan to do . . . For each solar system you'll able to define an ecliptic plane (referred to the ICRF) to which all orbits in the system will be referred. I think you're the first person to notice that this feature is missing . . .
