Description
English: Comparison of sizes of objects with size order of magnitude 1e16m: ten light year radius circle with yellow arrow; Bubble Nebula (NGC 7635), left; Dumbbell Nebula (NGC 6853), right; one light year shell lower right with the smaller Cat's Eye Nebula (NGC_6543) and Barnard 68 adjacent. All distances and sizes 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.
