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 plane...

7 planets orbiting a red dwarf star may be made of similar stuff Located about 40 light-years away, the red dwarf star, TRAPPIST-1 is home to the largest group of roughly Earth-size planets ever found in a single stellar system. Washington: The seven rocky planets orbiting the the red dwarf star TRAPPIST-1 have remarkably similar densities, which provides clues about their composition. Located about 40 light-years away, TRAPPIST-1 is home to the largest group of roughly Earth-size planets ever found in a single stellar system. Previous calculations determined that the planets are roughly the ...

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...
