Couple things about orbit drawing and classes

Post #1by xnk » 18.03.2004, 04:47

I propose we have a class "KBO" with its own orbit color etc. that we can use for things such as Sedna, Quaoar, and Varuna (and Pluto). I know Sedna isnt really a KBO because of its eccentricity, but it still would fit the new class better than any other. Right now i'm using the Moon class for these objects, which works all right. Comet puts a tail on them (no good) and Asteroid doesnt really do them justice.

Also - if you're more than 1 lightyear from the sun, you don't get to see any orbit paths. We've got comets like C/2001 C1 that have an aphelion at 1.57 LY from the sun and people are starting to make noise about the Oort Cloud going all the way out to 3 light years. Maybe if we could increase the cutoff distance a bit?

I labelled Sedna as a "planet" myself, just to make it easier to see in the morass of brown KBO orbits I have... :)

But yeah, it would be nice to have a new class with a different coloured orbit for these objects. :)

So why not also add an Oort class? It would also be nice to have subclasses such as the different types of asteroids and KBOs.

Or better yet...allow object classes to be added dyamically

Trojans
Mars Missions
Inner Oort cloud objects
etc.

Would be a nice feature to see!
