摘要

描述
Deutsch： Uranus (links), Neptun (rechts), Erde (links unten), Sirius B (mitten unten), und Venus (rechts unten), und noch kleinere Planeten, der Mond, und Zwergplaneten unten.
English： Uranus (left), Neptune (right), Earth (lower left), Sirius B (lower center), and Venus (lower right). The smaller planets, Earth's moon, and dwarf planets below, in decreasing size are Mars and Mercury, the Moon, Pluto, and Haumea. All are to scale. Note that the depiction of the white dwarf Sirius B's atmosphere is purely speculative. The relative brightnesses of the objects have been partly normalised. Adapted from Paul Stansifer's 1e7m comparison.png but using an updated figure for Sirius B's diameter.
Français： Uranus (à gauche), Neptune (à droite), Terre (en bas à gauche), Sirius B (en bas au centre), et Venus (en bas à droite). Les planètes plus petites et les planètes naines en-dessous, par ordre de taille décroissante sont Mars et Mercure, la Lune, Pluton, et la planète naine Haumea. Tous les objets sont représentés à la même échelle. Noter bien que la représentation d'une atmosphère sur la naine blanche Sirius B relève de la spéculation. La brillance relative des objets a été partiellement normalisée. (Adaptatio de l'image 1e7m comparison.png de Paul Stansifer, avec mise à jour du diamètre de Sirius B).

來源 derived from Paul Stansifer's POV-Ray source files (see below), by me, 84user, using POV-Ray, Celestia, and IrfanView. 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. 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. A generic asteroid texture from Celestia was used for Haumea. 84user's contribution (tweaking the numbers and getting textures) is public domain and source files used are described at 84user/Size comparison. Paul Stansifer's contributions to this image (mainly Sirius B) are available under the GPL, v. 2, and other licenses. See Paul Stansifer/Size comparison for more details and the other licenses.
