⭐ The seven planets of TRAPPIST-1 ⭐ Research published in 2017 in the journal Nature (NASA/JPL) 💫

TRAPPIST-1 is an dwarf star in the constellation Aquarius, and its planets orbit very close to it. The system has been revealed through observations from NASA's Spitzer Space Telescope and the ground-based TRAPPIST telescope, as well as other ground-based observatories. The system was named for the TRAPPIST telescope.

All seven planets discovered in orbit around the red dwarf star TRAPPIST-1 could easily fit inside the orbit of Mercury, the innermost planet of our solar system. In fact, they would have room to spare. TRAPPIST-1 also is only a fraction of the size of our sun; it isn't much larger than Jupiter. So the TRAPPIST-1 system's proportions look more like Jupiter and its moons than those of our solar system.
