Summary
Distribution of orbits for Centaurs.
Main graph
The position of an object represents
 its orbit’s semimajor axis a in AU (horizontal axis)
 orbit’s inclination i in degrees (vertical axis).
The size of the circle illustrates the object’s size relative to others. For a few large objects, the diameter drawn represents the best current estimates. For all others, the circles represent the absolute magnitude of the object.
The eccentricity of the orbit is shown indirectly by a segment extending from the left (perihelion) to the aphelion to the right. In other words, the segment illustrates the variations of the object's distance from the Sun. Objects with nearly circular orbits will show short segments while highly elliptical orbits will be represented by long segments.
Orbits of planets (Jupiter, Saturn, Uranus, Neptune and Pluto) are marked with white vertical bars. The bar labelled 1:2 shows the resonance with Neptune considered the edge of the main Kuiper Belt.
Histograms
Histograms show the population of objects with the parameter (eccentricity e and inclination i respectively) inside the given interval. The population is expressed in % of the total population (vertical axis)
 for inclination, the interval is 5^{o}, i.e. the first bar shows the relative population of objects with i in 05^{o} range, the next in 510^{o} range etc.
 for the eccentricity e, the interval is 0.1, i.e. the first bar shows the relative population of objects with e in 00.1 range (quite circular orbits)
 for semimajor axis a, the interval is 2AU i.e. the first bar shows the relative population of objects with e in 1012AU range.
