⧼wm-license-information-description⧽
English: Comparison of sizes of objects with order of magnitude 1e16m: ten light year radius shell with yellow Vernal Point arrow; below, white star Sirius 8.5 light years from Sun; on left, BL Ceti 8.73 light years distant; middle right, Proxima and Alpha Centauri about 4 light years distant; light year shell with Great January comet (Comet C/1910 A1)'s orbit shown as long extreme ellipse inside. All distances to scale, but stars are artificially enlarged for illustrative purposes only. No transparency version.

⧼wm-license-information-source⧽ 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.
