Encyclopedia

Planetary system is a set of gravitationally bound non-stellar objects in or out of orbit around a star or star system. Generally speaking, systems with one or more planets constitute a planetary system, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets, planetesimals and circumstellar disks. The Sun together with the planetary system revolving around it, including Earth, forms the Solar System. The term exoplanetary system is sometimes used in reference to other planetary systems. — Wikipedia

TRAPPIST-1 is an ultra-cool red dwarf star in the constellation Aquarius. It has a mass of about 9% that of the Sun, a radius slightly larger than the planet Jupiter, and a surface temperature of about 2,566 K (2,293 °C). The star is located at a distance of 40.7 light-years (12.47 pc) from the Sun and is estimated to be 7.6 billion years old, making it older than the Solar System. — Wikipedia
