Outer planets & Pluto

Major planet positions are calculated by the VSOP87 method (J. Meeus, Astronomical Algorithms, Willmann-Bell). Positions of Pluto are calculated from the latest osculating elements given in the Minor Planet Centre's database. Star data are from the Hipparcos/Tycho databases.

The printed Handbooks have always plotted the outer planets on the coordinate system for the mid-year (eg, J2012.5). Here we have used J2000.0 in the hope that it is more useful in practice. Some feedback would be useful.
