- 1st Phase: A “large” comet’s inactive nucleus, rotating and seen in a close-up view, modeled according to the shape and features of actual large comet nuclei (Halley, Borelly, Tempel 1, Wild 2)
- 2nd Phase: The comet becomes active, while the camera moves away from the nucleus quickly and leaves the developing coma. Proportions are rendered realistically.
- 3rd Phase: The ion and dust tails develop, while the comet is shown in full view (i.e. the animation neither shows the comet’s orbit nor the sun; we suggest to show this animation before or after a separate illustration of a comet’s orbit). Both tails are realistically modeled according to imagery of “large” comet tails, especially Hale-Bopp.
