Exoplanets sizes: TRAPPIST-1 versus the Solar System

thingiverse

This is a script that generates models of the star and planets in a planetary system; I've used it to generate models for our solar system and for TRAPPIST-1, a system with many earth-like planets around a much smaller star. These models are to the same physical scale, so the (piece of the) Sun is in proportion to the star of TRAPPIST-1, as are all the planets. The script is included and allows you to generate such models at any scale and of other planetary systems for which you know the sizes. I recommend, as I did, printing TRAPPIST-1 in red rather than the yellow of the Sun, because TRAPPIST-1 is a much redder star - an ultracool dwarf. For more on TRAPPIST-1, see [here](http://www.trappist.one/) or [Wikipedia](https://en.wikipedia.org/wiki/TRAPPIST-1). This thing is inspired by [fc_tea](https://www.thingiverse.com/tc_fea/about)'s [Sun and Planets to scale](https://www.thingiverse.com/thing:1430614) but I wrote the script from scratch and used planet details from Wikipedia, thus discarding any sensible aesthetic choices in the original.
