Category:Nebulae

This category lists nebulae.

Note: For the sake of simplicity, the dimensions of nebulae in Starship Tracker are perfectly identical from the top to the bottom.

• If a nebula exists completely within one sector plane (ex: 0.00 to 20.00): its Z-coordinates will all match that determined to be its base (i.e., its center) z-plane.
• If a nebula crosses over into one additional sector plane: it will have two representations: one each on the Z-planes representing the top and the bottom of the nebula, with the designated z-coordinates. The (exact) base z-plane will not be represented, though the nebula's Name will be centered on that base z-plane (at the nebula's geographical center), on the original representation (with a font size of 75%). Each of the two location databases will be titled with "(top)" or "(bottom)" appended to the Name. The secondary representation's Name will be located at the top or bottom (as appropriate) of the nebula's z-axis (at 50% font size).
• If a nebula crosses over into more sector planes than two: the base plane will be titled only with the location name, with the z-coordinates of that plane matching that determined to be its base (i.e., its center) z-plane. The top and bottom planes will be represented with locations titled "(top)" or "(bottom)" appended to the Name and all intermediate sector planes will have the "floor" of that sector plane appended to the Name (ex: "J'ral Nebula (-20)"). The z-coordinates of the top and bottom representations will match those designated and intermediate sector-plane locations will have the z-coordinates match the mid-range of that sector plane (ex: for -20.00 through -0.01, it would be set at -10.00).

Dimensions Determination Method

1. Provide Perplexity the dimensions of the nebula/star cluster/state's established coordinates of its central plane:

A closed asymmetrical shape is represented on a 2D map with the following (JSON format) coordinates. Generate that 2D representation as an image with a defining boundary.

Attach those points; ex:

"points":[{"x":-31.16,"y":10.75,"z":0},{"x":-32.15,"y":8.55,"z":0},{"x":-29.8,"y":7.14,"z":0},{"x":-27.71,"y":10.75,"z":0},{"x":-26.6,"y":12.82,"z":0},{"x":-28.14,"y":12.51,"z":0}]

Confirm the provided image roughly matches the actual shape in SST.

2. Determine the relative center of the the nebula/star cluster/state:

What is the coordinate for the geographic center of this shape?

3. Determine the greatest length between established coordinates of the nebula/star cluster/state:

What is the longest dimension that exists within this shape?

4. Determine the upper and lower z-axis values, based on that greatest length; modify as necessary/pertinent.

5. Determine the approximate volume by the central plane's established dimension and the greatest length doubled:

Calculate the volume of a large irregular diffuse nebula (not bipolar) with a fractal boundary and vertical extent of ## units (crossing through the geographic center), using the defined cross-sectional area as the base.
