Description
English: Comparison of sizes of lengths with order of magnitude 1e15m: light year shell (largest yellow sphere with yellow Vernal point arrow as radius); Comet 1910 A1's orbit (long yellow extreme ellipse to left); light month shell (inner yellow sphere) with Hyakutake's orbit inside. All to scale. No transparency version.

derived from Paul Stansifer's POV-Ray source files (see below), by me, 84user, using w:en:POV-Ray, and w:en:IrfanView.

84user's contribution (inside POV-Ray files: adjusting coordinates, changing light source and other parameters) is public domain and source files used are described at User:84user/Size comparison.

Physical information is based on the Wikipedia articles and elsewhere (see POVRay source files) about the respective lengths.

Paul Stansifer's contributions to this image (POV-Ray code) are available under the GPL, v. 2, and other licenses. See User:Paul Stansifer/Size comparison for more details and the other licenses.

This space image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “1e15m comparison light year month comet 1910a1.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
