Request Can someone teach me how to add an atmoshphere to a planet?

[Xavier]

I just want to add an atmosphere to Pluto and Charon.
Can someone point me in the right direction?

I have this addon -

I think the "API_Guide.pdf" in the Orbiter SDK has a pretty good guide on this, you could also look at "Earth.cfg" in the config directory (or any other planet) for an example of what you need to set / how to set it.

Here is an example with the Mars config:

; === Configuration file for planet Mars ===
Name = Mars
Module = Mars
ErrorLimit = 1e-5
SamplingInterval = 138 ; interpolation sampling interval
; (interpolation error ~1m)
; === Physical Parameters ===
Mass = 6.418542e+23
Size = 3.38992e6 ; mean radius
JCoeff = 0.001964 ; J2 coefficient for gravitational potential
AlbedoRGB = 1.0 0.7 0.3
; === Rotation Elements ===
SidRotPeriod = 88642.6632 ; 24.622962 hours
SidRotOffset = -0.757 ; by Chode - determined from the sun rise and
; set times for Spirit and Opportunity
Obliquity = 0.4663 ; obliquity of ecliptic (26.72°)
LAN = 4.5865 ; longitude of solar transit (262.78°)
; === Atmospheric Parameters ===
AtmPressure0 = 0.61e3 ; pressure at zero altitude [Pa]
AtmDensity0 = 0.02 ; density at zero altitude [kg/m^3]
AtmGasConstant = 188.92 ; specific gas constant [J/(K kg)]
AtmGamma = 1.2941 ; specific heat ratio c_p/c_v
AtmAltLimit = 100e3 ; cutoff altitude
AtmColor0 = 0.51 0.40 0.28
AtmHazeColor = 0.35 0.35 0.4
AtmHazeDensity = 1.5
; === Visualisation Parameters ===
MaxPatchResolution = 10 ; highest sphere patch level

What you need to worry about is underlined. Copy the atmosphere lines from Mars to Pluto and mess with it to get the atmosphere to your liking.

By the way, to the Forum.
