TRAPPIST-1, also designated 2MASS J23062928-0502285, is an ultra-cool red dwarf star that is slightly larger, but much more massive, than the planet Jupiter; it is located 39.6 light-years from the Sun in the constellation Aquarius.

Some of my Csiro colleagues are jazz musicians.

Resonant chain … Hmm … I wonder if that can telp us anything about the ellipticity of orbits?

I don’t like the way that computations of planetary orbits go unstable. Remember Veiikovskiy. It’s a numerical problem that has no physical reality.
