[edit] Summary
Near Scattered Disk Objects. Kuiper Belt shown in grey, resonant objects, other than plutinos, shown in green. Extreme orbits plotted in yellow. Generated by a program written by Eurocommuter.
[edit] Main graph
The position of an object represents
- its orbit’s semi-major 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.
Main resonances with Neptune are marked with vertical bars; 1:1 marks the position of Neptune’s orbit (and its Trojan asteroids), 2:3 marks the orbit of Pluto (and its moons) etc.
