Writing the Initial Template File

To simulate our own system, we'll need to write a template file for it first. You can include any number of planets, in any formation you want. You can set the limit to some random value for now, as we don't know how long it'll take each planet to finish it's orbit.

Here''s an example template file:

{
    "name": "my-solar-system",
    "limit": "3yr",
    "delta": "1hr",
    "t": 0,
    "bodies": [
        {
            "name": "Sun",
            "mass": 1.989e30,
            "radius": 6.95e8,
            "r": [[0, 0, 0]],
            "v": [[0, 0, 0]]
        },
        {
            "name": "Earth",
            "mass": 5.972e24,
            "radius": 6.371e6,
            "r": [[1.496e11, 0, 0]],
            "v": [[0, 0, 2.98e4]]
        },
        {
            "name": "Moon",
            "mass": 7.342e22,
            "radius": 1.737e6,
            "r": [[1.499844e11, 0, 0]],
            "v": [[0, 0, 3.082e4]]
        }
    ]
}

Be sure that you set the limit to a number that will surely be more than the longest orbital period, so axana can correctly find a good limit.
