The red dwarf star TRAPPIST-1 is home to the largest group of roughly Earth-size planets ever found in a single stellar system. Located about 40 light-years away, these seven rocky siblings provide an example of the tremendous variety of planetary systems that likely fill the universe. A new study published in the Planetary Science Journal shows that the TRAPPIST-1 planets have remarkably similar densities. That could mean they all contain about the same ratio of materials thought to compose most rocky planets, like iron, oxygen, magnesium, and silicon.

Just 40 light-years from Earth is a planetary system that has intrigued scientists since its discovery in 2016. While some of the planets in this system will be observed by the upcoming James Webb Space Telescope, scheduled to launch in October, researchers continue to uncover new details that make TRAPPIST-1 even more distinct. The planets, which are too small and faint to be seen by any current ground or space-based telescopes, have such similar densities that they may have equally similar compositions, new research has suggested.

TRAPPIST-1 s 7 Rocky Planets May Be Made of Similar Stuff The Universities of Bern, Geneva and Zurich have made astonishing discoveries about the composition of the planets of the star TRAPPIST-1. © Lead Art, Nasa/ JPL-Caltech. The TRAPPIST-1 star is home to the largest batch of roughly Earth-size planets ever found outside our solar system. An international study involving researchers from the Universities of Bern, Geneva and Zurich now shows that the exoplanets have remarkably similar densities, which provides clues about their composition. Discovered in 2016 some 40 light-years away, the seven exoplanets orbiting the star Trappist-1 offer a glimpse at the tremendous variety of planetary systems that likely fill the universe.
