文件:1e8m comparison Saturn Jupiter OGLE-TR-122b with Uranus Neptune Sirius B Earth Venus no transparency.png

derived from Paul Stansifer's POV-Ray source files (see below), by me, 84user, using POV-Ray, Celestia, and IrfanView. Non-transparency version.

Planetary texture maps (with the exception of Earth) and Earth's cloud map were from Celestia version 1.5.1 dated 2008-04-06, used under the GPL, version 2, and so makes the whole image GPL-V2. Earth's surface is a monthly Blue Marble Next Generation image from NASA, and thus public domain. Uranus atmosphere was faked from a one pixel vertical slice stretched out to a texture map (to get a colour range) from NASA's public domain image taken by Voyager 2. Venus atmosphere is from JPL-Caltech's clone of a Mariner 10 image at http://maps.jpl.nasa.gov/venus.html, created by Seal. Neptune atmosphere is fictional texture by Don Davis, owned by JPL/Caltech at http://maps.jpl.nasa.gov/neptune.html. Saturn's rings were adapted from NASA/ESA's Cassini imagery PIA08361 Ring World.png.

84user's contribution (getting textures, partly circularising and enhancing the rings; and inside POV-Ray files: adjusting coordinates, changing light source and other parameters) is public domain and source files used are described at 84user/Size comparison.

Physical information is based on the Wikipedia articles about the respective bodies. The colour of OGLE-TR-122b is based on an artist's rendition at [1]
