I don't have all of them in Celestia by any means, but this is a sample.

I use a script to turn show them.

Code:
-- Title: Mark Stars with Planets
--
-- Author: Harald Schmidt, 2004
-- http://celestia.h-schmidt.net/
--
-- comments, bugreports to: celestia ( at ) h-schmidt.net
--
-- You are free to use, copy, modify, redistribute or do whatever you want with this script,
-- but a credit to the original author would be nice.
--


function checkstar(star)
    children = star:getchildren()
    if table.getn(children) > 0 then
        star:unmark()
        star:mark("#00ff00", "circle",8)
    end
    return
end


t = celestia:getscripttime()
check_interval = 1000

i = 0
j = check_interval

cnt = celestia:getstarcount()

celestia:setrenderflags{markers=true}

while i < cnt do
    local star = celestia:getstar(i)
    checkstar(star)
   
    i = i + 1
    -- Avoid staying too long in the loop,
    -- then Celestia would forcefully stop this script
    if i >= j then
        j = j + check_interval
        t0 = celestia:getscripttime()
        if t0 - t > 0.2 then
            wait(0.0)
            t = t0
        end
        celestia:print("Checked " .. i .. " stars")
    end   
end

celestia:print("Done")

I found a better exoplanets DB here:

https://celestiaproject.net/forum/viewt ... =6&t=17470

It seems to be WIP but has many more exoplanets than the ones I had!

I had a look at that add-on a while back, it doesn't do the required orbit transforms so the transiting planets will not transit. This is a common problem with exoplanet add-ons for Celestia, e.g. almost all of the exoplanet add-ons on the Celestia Motherlode suffer from this issue.

I'm planning some major upgrades to my Python scripts in the near future, including code to retrieve TYC identifiers so that it can be used together with the Gaia DR1 data.

Thanks ajtribick.

I just found this:

http://exoplanetarchive.ipac.caltech.ed ... ig=planets

But I personally have limited experience getting all this data into stc and ssc files for celestia. :oops: :wall:

I would like to delve more into Astrophysics. I have been an amateur astronomer since I was 15, but have no formal education in soace sciences.
All of my post secondary education is in Computer Science.

I have purchased Mikhail Marov's The Fundamentals of Modern Astrophysics and have started reading it.

:DD

Good to learn about your new interests. You may always discuss things by PM if you prefer. Have you e.g. read this report by Dawoon (aka dirkpitt)?
Gravitational Lensing project: an academic success story,
just to let you have an idea what sort of things are possible in principle...

Cheers,
Fridger

Thanks Fridger.
The above should read Space Sciences not "Soace" (sic) Sciences.
The keys on my keyboard are to small for my fat fingers! :evil:
