Some of my Year 6 students are trying to create a solar-system project
.They have commented that similar projects on the web have the planets
moving in circular orbits but my students want to be as
astronomically-correct as possible and use more elliptical orbits . The
problem is that I don't know a 'formula' to get turtle to move in an
elliptical-type path. I'd very much appreciate any assistance from
cyberspace.  Thanks  Graham Williams  Victoria  Australia
