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

These inner solar system diagrams show the positions of all numbered asteroids and all numbered comets on 2018 January 1. The orbits and positions of the planets Mercury, Venus, Earth, Mars, and Jupiter are also shown. Asteroids are yellow dots and comets are symbolized by sunward-pointing wedges.

The top diagram shows the view from above the ecliptic plane (the plane containing the Earth's orbit). 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.
