Thanks for the heads up
I have tried to load the ephemeris of 2009DD45 into Stellarium 10.1 but seem to be having problems !
Any advice on what I am doing wrong will be gratefully received !
I have grabbed the Horizons data and after many attempts all resulting in the same error :
"Microsft Visual C++ Runtime Library
Runtime Eror
Program C:\ . . etc etc . . . stellarium.exe
This application has requested the Runtime to terminate it in an unusual way.
Please contact the applications support team for more information"
Have ocme to th einescapable conclusion that i have stuffed it !
I have tried entering both elliptical and comet orbits with all the specific data for each of them but to no avail - always the same error.
The last data I tried using a comet orbit
[2009DD45]
name = 2009DD45
coord_func = comet_orbit
orbit_Eccentricity = .2658677749332017
radius = 1035.
oblateness = 0.0
albedo = 0.8
lighting = true
halo = true
color = 1.0,1.0,1.0
tex_halo = star16x16.png
tex_map = deimos.png
orbit_TimeAtPericenter = 2454896.753178004
orbit_PericenterDistance = .9910206185457694
orbit_Eccentricity = .2658677749332017
orbit_ArgOfPericenter = 153.7105864337799
orbit_AscendingNode = 172.8882311801781
orbit_Inclination = 13.2335895640192
The elliptical orbit data I used included :
orbit_Epoch = 2454891.5
orbit_Period = 1.56845
orbit_SemiMajorAxis = 1.349921151405112
orbit_AscendingNode = 162.0453593489365
orbit_LongOfPericenter = 166.143873878825639
orbit_MeanLongitude = 522.842736579213139
substituting for some of the Comet orbit data
Thanks
