Named TRAPPIST - 1 because it was discovered by the Transiting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile, the star is an ultra-cool M - type dwarf star with eight percent the mass of the Sun and half its temperature, located in the direction of the constellation Aquarius.

The planetary system was named TRAPPIST - 1 after The Transiting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile.

While putting together these planetary puzzle pieces, the scientists also determined that the dark family's original planetesimals were no smaller than 35 kilometers across.

In contrast to earlier observations the team did not observe dust that will later form into planets, but dust created in collisions between small planets of a few kilometres in size — objects called planetesimals that are similar to the asteroids and comets of the Solar System.

Planets and planetesimals (small planets and large asteroids) are formed primarily from silicate rocks and metal.

«Many of these systems may have formed similarly to Kepler - 223, but then later became destabilized, perhaps by a more distant massive planet or perhaps by the cumulative effect of the scattering of many smaller planetesimals left over from the planet - building process.»

That's why a number of ideas have been proposed recently for speeding up core formation, by efficient accretion of either cm - or mm - sized «pebbles» early on, or small fragments and debris resulting from planetesimal collisions at later stages.
