Distant Solar System Orbit Diagrams
Below are diagrams of the distant solar system on
2018 January 1.
of these diagrams is given at the bottom of this page.
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,
and comets Halley
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.

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.
