Unless otherwise stated, the animations are drawn as seen from the north ecliptic pole with the vernal equinox off to the right.
The animations are currently available as animated GIFs (in two different sizes), other formats may be added in the future.
Any use of these animations for anything other than your own personal enjoyment is not permitted without our express permission.
This animation shows the motion of objects in the inner region of
the solar system over a two-year period at 10-day intervals. The sun is the
yellow symbol at the center of each frame. The orbits of the planets Mercury,
Venus, Earth and Mars are shown in light blue, with the current locations of
each planet being shown by large crossed circles. Main-belt minor planets
are shown as green circles, Near-Earth asteroids as red circles. Comets
are shown as blue squares (filled for numbered periodic comets, outline for
other comets).

This animation shows the motion of objects in the inner- to mid-region of
the solar system over a two-year period. The animation shows objects out
to the orbit of Jupiter and a little beyond. The meaning of the symbols
is as for the Inner Solar System animation: additionally, Jupiter and its
orbit are now shown and the Jupiter Trojans, which orbit in the same
orbit as Jupiter but roughly 60 degrees ahead or behind the planet, are
colored blue.
This animation shows the vast bulk of the objects tracked by the MPC. The total number of objects shown is more than 100000.

This animation shows the motions of objects in the outer solar system,
beyond the orbit of Jupiter, over a 100-year period at 200-day intervals.
The orbits and current locations of the Jovian planets (Jupiter, Saturn,
Uranus and Neptune) are shown. The current location of Pluto is indicated
by the large white crossed circle. High-eccentricity objects are shown
with cyan triangles, Centaurs as orange triangles, Plutinos as white
circles, "Classical" TNOs as red circles and Scattered-Disk Objects as
magenta circles.
NOTE: The strange behavior exhibited by the comets (a general heading inwards prior to the mid 1990s and a general heading outwards post 2000) is a consequence of plotting only those comets currently observable (as of mid 2002). Around this date, all of the long-period comets would have been at or near perihelion. Fifty years either side of this date they are all far from the sun. If the full cometary catalogue had been plotted, this effect would not be so noticeable as there would be inbound and outbound comets visible on each pre-2002 frame.

This animation hitches a ride on the earth and observes its near-space
environment for a period of one year at daily intervals starting in July 2007.
No objects
are displayed that are more than 20 million km from the earth. Objects
within one-third of this distance are colored red, objects within
two-thirds are colored orange, other objects are green. Objects below the
ecliptic plane are shown as outline circles, objects above as filled circles.
Objects may appear and disappear in seemingly odd locations, depending on how
their orbits intersect the sphere enclosing the volume of space within
20 million km of the earth.
Notable close approaches during the period occur on

Most of the objects depicted in this
animation are recent discoveries.
The symbol representing Earth is not to scale: at the scale of these plots, the earth would be about a quarter pixel across on the larger plot and about a tenth of a pixel on the smaller plot.

animation are recent discoveries. The apparent dearth of objects after the
start of September is caused by the fact that we haven't yet discovered
most of the objects that will making close approaches in the months ahead:
the only objects displayed are those that were discovered in previous
years.
