Plot of the Inner Solar System The plot below shows the current location of the major planets (Mercury through Jupiter) and the minor planets that are in the inner region of the solar system. Also available is a view of the innermost region of the solar system . The plot is of the same form as the plot on this page. An animated version of this plot is available from our Animations page. This plot must not be reproduced without the express written consent of the Minor Planet Center Jupiter Trojans , here colored deep blue. Numbered periodic comets are shown as filled light-blue squares. Other comets are shown as unfilled light-blue squares. In this view, objects in direct orbits (most of the objects in this plot) move counterclockwise and the vernal equinox is towards the right. (The equinox directions are the direction of the sun as seen from the earth.) The plot is correct for the date given at the bottom of the plot. Back to minor planet lists and comet lists Credits.

82. Plot Of The Outer Solar System Plot of the Outer solar system. The plot below shows the current locationsand orbits of the Jovian planets (Jupiter through Neptune http://cfa-www.harvard.edu/iau/lists/OuterPlot.html

Plot of the Outer Solar System The plot below shows the current locations and orbits of the Jovian planets (Jupiter through Neptune) and the current locations of various distant minor bodies. An animated version of this plot, showing the motion of the objects over a 100-year time period, is available from our Animations page. This plot must not be reproduced without the express written consent of the Minor Planet Center The orbits of the planets are shown in light blue and the current location of each object is marked by large dark-blue symbols. The current location of the minor bodies of the outer solar system are shown in different colors to denote different classes of object. Unusual high-e objects are shown as cyan triangles, Centaur objects as orange triangles, Plutinos (objects in 2:3 resonance with Neptune) as white circles (Pluto itself is the large white symbol), scattered-disk objects as magenta circles and "classical" or "main-belt" objects as red circles. Objects observed at only one opposition are denoted by open symbols, objects with multiple-opposition orbits are denoted by filled symbols. Numbered periodic comets are shown as filled light-blue squares. Other comets are shown as unfilled light-blue squares. Dual-status objects are shown as minor planets. In this view, objects in direct orbits (most of the objects in this plot) move counterclockwise and the vernal equinox is towards the right. (The equinox directions are the direction of the sun as seen from the earth.) Details of the designations are given in the

Related Web Sites Introduction Since the first Egyptian farmers discovered the annual reappearence of Sirius just before dawn a few days before the yearly rising of the Nile, ancient civilizations around the Mediterranean have sought to explain the movements of the heavens as a sort of calendar to help guide them conduct earthly activities. Counting phases of the moon or observing the annual variations of daylength could, after many years' collection of observations, serve as vital indicators for planting and harvesting times, safe or

92. Meadow View Observatory A collection of color ccd images of galaxies, nebulae, star clusters and solar system objects. http://www.astroimager.com/

Welcome to Bill Walser's Meadow View Observatory The observatory saw first light 15 May 1999 and is located in central North Carolina. It was motivated by love of deep space color images and my frustration over setting up and taking down telescope and computer equipment every clear night (Ignoring the issues of bugs, heat and ice). Total construction time was about two months including the dome, its base and the control cabin. It now takes less than ten minutes to start imaging. The dome is a ten foot ProDome and the cabin is a twelve foot square kit available through Lowe's. The cabin can be close to the dome because the ring of trees around the meadow raises the horizon thirty degrees in all directions. Some of the images included are early efforts (some obviously so). The learning curve for this type of imaging is difficult because of the broad range of knowledge required and a considerable amount of "hands on" doing (and frustration). Although some are technically weak they are still beautiful. You are visitor number
