Here's Celestia's SSC catalog that i used.
It'd be more appropriate for the world to be orbiting around some other star, of course, with its own orbit, year and day lengths.

Code:
"World" "Sun"
{ 
  Radius 6453.229 # km; circ = 40546.8 km
  Texture "world.*"

  EllipticalOrbit { SemiMajorAxis 1 Period 1}

  UniformRotation
	 {
	    Period         24
	    Inclination    20
	 }
}

AltSurface "Relief" "Sun/World" 
{
	   Texture "relief.*"
}

AltSurface "MeanTemp" "Sun/World" 
{
	   Texture "mean_temp.*"
}

AltSurface "AvgRainfall" "Sun/World" 
{
	   Texture "avg_rainfall.*"
}

AltSurface "Zoom" "Sun/World" 
{
	   Texture "zoom.*"
}

AltSurface "Color" "Sun/World" 
{
	   Texture "World_Color1.*"
}
