Gives me is significantly different from what I've found in another source (like a magazine, or an on-line ephemeris). What's the problem?

This is almost certainly the result of using outdated orbital elements for the asteroid, comet, or spacecraft in question. Voyager 4.5 and SkyGazer 4.5 lets you automatically download and import the latest comet/asteroid/satellite orbit files from the Minor Planet Center and other sources; use the Updates command in the Voyager 4.5 or SkyGazer 4.5 menu (Mac OS X) or Help menu (Windows). Please note that your software must be registered in order to download data updates; unregistered versions have a fixed set of orbits that cannot be updated.

Because of the gravitational perturbations of the other planets, the orbit of any object in the solar system is always changing. Therefore, a single set of orbital elements will gradually become less accurate over time. However, most asteroid and comet orbits change slowly enough that predictions based on a single orbit should be good to about an arcminute for several years, which ought to be sufficient for locating them in the sky.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
