Only for Sun, Earth and Mars, but here's an interactive Flash that illustrates it graphically. Third link from the top "Part I, Equivalence of Hypotheses (Flash)" Note that the planets don't move as you move the mouse over the image, only the circles (the theory) change. http://science.larouchepac.com/kepler/newastronomy/ If you move the mouse pointer to ...


Data from observatory archives is a good way to go. Here is another one with tons of imaging datasets: http://archive.eso.org


In addition to the capture mechanisms mentioned by Andy, you also need to take into account the stability of any orbit due to perturbations from tidal effects. E.g. in case of our Moon, there are no stable orbits possible. Every satellite put in orbit around the Moon had had to implement course corrections to prevent it from prematurely crashing into the ...


This is due to the mechanics of capture. For one object (moon) to be captured by a another (planet), some energy has to be removed from the system. If the incoming moon has an existing satellite then it would be ejected, carrying a lot of kinetic energy. If a small body were to be captured by the planet/moon combination, it would usually be captured by ...


It's pretty easy to create a dataset for yourself using remotely controlled telescopes. I've used iTelescope in the past and had a good experience. Their "starter" account costs $20 and should be good to get you going.


Try the NASA data catalog, https://data.nasa.gov/data. Also Try the Keck Observatory Archive, KOA, http://nexsci.caltech.edu/archives/koa/index.shtml. Look for raw images. of clusters or galaxies.


You could use archival data, e.g., from the WISE mission: http://irsa.ipac.caltech.edu/applications/wise/ The data are reduced as well as photometrically and astrometrically calibrated, which should make the image combination a lot easier. Just type in random coordinates and download data for a field with the desired number of frames. You can also try ...
