| Description |
English: Comparison of sizes of lengths with order of magnitude 1e14m: light month shell (largest yellow sphere with Comet 1910 A1's orbit passing through top left); Hyakutake's orbit (long orange extreme ellipse); light week shell (inner yellow sphere with yellow Vernal point arrow as radius); and Sedna's orbit (yellow ellipse inside the light week shell). Shorter 1e13 m distances are: comet Hale Bopp's orbit (faint small orange ellipse below); and one light-day (smallest yellow spherical shell). All to scale. No transparency version.
