[edit] Summary
Illustration of colors of Centaurs. Plotted by a program written by Eurocommuter.
- 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; no albedo differences are currently displayed, in spite of the graph's title!
- 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.
- for Phoebe, Triton, and Mars (yellow labels), size is not shown to scale.
