    YU55's close flyby in Celestia

    First, save the following text as a file called "2005YU55.ssc" in /usr/share/celestia/extras
    Code:
    "2005 YU55" "Sol"
    {
    Class "asteroid"
    Mesh "ky26.cmod"
    Texture "asteroid.jpg"
    Radius 0.4 # maximum semi-axis
    MeshCenter [ -0.000718 -0.000099 0.000556 ]
    
    InfoURL "[url]http://en.wikipedia.org/wiki/2005_YU55"[/url]
    
    EllipticalOrbit
    {
    Epoch 2455800.5 # Epoch 2011 Aug. 27.0
    Period 1.22
    SemiMajorAxis 1.1427166
    Eccentricity 0.4289481
    Inclination 0.51346
    AscendingNode 39.31601
    ArgOfPericenter 268.77407
    MeanAnomaly 348.84963
    }
    
    RotationPeriod 0.9
    
    Albedo 0.15
    
    }
    Then you can sit on YU55 while it flies by the Earth-Moon system, or on the Earth, or above or below. While YU55 comes closer to the Earth than the Moon, on 11/8/11 at about 21.36UT, it does not come between the Earth and Moon. It's below the plane of the Earth-Moon system by a significant distance. No danger of collision.

    Some screen captures from Celestia.
    The red orbit is YU55. The Green is the Moon. The main Blue one is the Earth.
    YU55 does not plunge through the plane of the Moon's orbit around the Earth. At it's closest point it is nearest to Australia, but well below the plane of the Moon's orbit, as you can see.

        Hi GreyGeek....

        What should the file type be? Saving it as a text file doesn't seem to work. I have no idea on how to create a .ssc file.

          It is a text file, but you have to save it with the .ssc extension. Nothing more. Because of where it is being saved, you need to create the text file 'as root' in order to save it in /usr/share, or, create it and save in as your non-root user first, and then move it to the location specified 'as root'.

            What Snowhog said, and ...

            Code:
            sudo cp /home/path/to/file/2005YU55.ssc /usr/share/celestia/extras

              Hi...

              Thank you both for your help but how do you do this exactly? Right now, I'm only using Windows Vista with the corresponding version of Celestia (1.4.1.)

              Thanks...

                First you select the text, then open open KWrite or Kate and paste the text into the file. Then select "Save As ..." and save it to your home directory using 2005YU55.ssc as the name. Then open a Konsole and issue the command I gave in a subsequent post:
                Code:
                sudo cp /home/path/to/file/2005YU55.ssc /usr/share/celestia/extras
                Or you could open KWrite or Kate as root:
                kdesudo Kwrite
                paste the script into the file, then select "Save As...", fill in the name "2005YU55.ssc", navigate to the /usr/share/celestia/extras directory, and save it.
