The image below shows a schematic of our solar system viewed from
above, where 50 AU is 50 times the average Earth-Sun distance.
The yellow dot indicates the position of the Sun.
The colored lines indicate the orbits of Jupiter (white),
Saturn (red), Uranus (green), Neptune (Blue), Pluto
(cyan), and a scattered KBO (magenta).
When the orbits of KBOs pass to close to Neptune, Neptune's
gravity scatters them outward and produces a scattered KBO.
The cyan points indicate the positions of known KBOs as of January 2004.
