Distant Solar System Orbit Diagrams

Below are diagrams of the distant solar system on 2018 January 1. A description of these diagrams is given at the bottom of this page.

Distant Solar System Diagram (top view)

Distant Solar System Diagram (edge view)

These distant solar system diagrams show the positions of objects with semi-major axes (a) greater than 6 AU (orbital periods greater than ~15 years) on 2018 January 1. The orbits and positions of Jupiter, Saturn, Uranus, Neptune, Pluto, Eris, Sedna, and comets Halley and Hale-Bopp are also shown. The orbits of objects beyond Neptune are drawn using two slightly different colors; the brighter color is used for the portion of the orbit above the ecliptic plane. Trans-Neptunian objects larger than about 700 km in diameter are shown as white diamonds, comets are sunward-pointing wedges, and the other objects are yellow dots.

The top diagram shows an oblique view from above the ecliptic plane. The bottom diagram shows the view from the edge of the ecliptic plane. In both diagrams, the vernal equinox is to the right along the horizontal axis (+X direction). Only comets and asteroids in JPL's small-body database as of 2018 January 1 were used.

Postscript versions of these diagrams: view from above, view from the edge.
