The seven planets orbiting the ultracool dwarf star TRAPPIST-1 are mostly rocky, with some potentially holding more liquid water than Earth.

New research reveals the density of the worlds within this crowded system to a greater precision than ever before. The findings reveal that some of the planets could have up to 5 percent of their mass in liquid water form, about 250 times as much water as found in Earth’s oceans.

“All the TRAPPIST-1 planets are very Earth-like — they have a solid core, surrounded by an atmosphere,” Simon Grimm, an exoplanet scientist at the University of Bern in Switzerland, told by email. Working with a team of researchers, Grimm precisely modeled the densities of the seven worlds. [Meet the 7 Earth-Size Exoplanets of TRAPPIST-1]
