slim chance
My name is Slim and I'm retired. I don't have a good scientific background, having worked in construction most of my life. I live at 7 degrees north of the equator and take photographs of flora, fauna, and insects (especially insects) as a hobby. I once took an autocad class and plotted the sun & planets for a project and was very surprised to see how far apart all the celestial bodies were. I'd like to repeat the exercise to show my young relatives how small everything is compared to the space it occupies. I'm on SS (fixed income) and can not afford to download an autocad program.
