TheTransneptunians_Color_Distribution.svg‎ (SVG file, nominally 450 × 300 pixels, file size: 98 KB)

Illustration of colour distribution of the trans-Neptunian objects. Plotted by a program written by Eurocommuter. For reference, two moons: Triton and Phoebe, the centaur Pholus and planet Mars, are plotted in yellow (size not to scale).

Quaoar and Varuna with similar sizes and color indices are covering each other

[edit] Graph

  • The position of an object represents the two colour indices
    • horizontal axis V-B, blue colour index i.e. the difference in the magnitude of the object observed through a visual (green-yellow) and a blue filter
    • vertical axis R-V, red colour index, the difference in the magnitude between red and visual filters
  • colour (slightly enhanced) represents the hue of the object;
  • the size of a sphere illustrates the object’s size relative to others.
    • for a few large objects, the diameter drawn represents the current estimates (for known albedos)
    • for all the others, the diameter represents the absolute (V) magnitude of the object.
