English: Comparison of size of Betelgeuse (largest dull-red sphere inside Jupiter's orbit) and R Doradus (red sphere shown inside Earth's orbit) together with the orbits of Mars, Venus and Mercury and the stars Rigel and Aldebaran from Image:1e10m comparison Rigel, Aldebaran, and smaller - antialiased no transparency.png, to scale.

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: adapting Paul's star macros for Rigel and Aldebaran, 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 bodies, and most star colours taken from http://www.vendian.org/mncharity/dir3/starcolor/.

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