Planetarium with zoom and moving planets

[Stellaferox]

Hi All,

I made an application to show all the planets in the solar system with a zoom-possibility. The application doesnot have a help-function but the use is pretty straightforward.
Lefttop is the dat which can be altered to view the position of the planets on that particular date. Next to it is the Julian Daynumber from which the positions are computed. Next to that (topright) is the date which alters as the simulation is started. underneath that is the reset-button to get back to today and the checkbutton to show the names of the planets.
The play-button advances with a day (planets turn counter-clockwise). The fastforward anf fastbackward go with a week.
Have fun!
I'd like to thank Klaus for helping me out on issues in the past.
Don't hesitate to comment as this application is far from being ready! In the future small pics of the planets are planned, with some other features. Suggestions are welcome.
