TL;DR: The observations reveal that at least seven planets with sizes and masses similar to those of Earth revolve around TRAPPIST-1, and the six inner planets form a near-resonant chain, such that their orbital periods are near-ratios of small integers.

TL;DR: The TRAPPIST-1 system is the first transiting planet system found orbiting an ultra-cool dwarf star as discussed by the authors, which was unconstrained until now, and has a radius of 0.727 Earth radii and an equilibrium temperature of 173 K.
