@nebulaspace_: The TRAPPIST-1 system, located about 39 light-years away in the constellation Aquarius, is renowned for its seven Earth-sized planets. Discovered by the TRAPPIST (Transiting Planets and Planetesimals Small Telescope) telescope, this system features a central ultra-cool dwarf star, TRAPPIST-1, which is only slightly larger than Jupiter and emits significantly less radiation than the Sun. The seven planets, named TRAPPIST-1b through TRAPPIST-1h, are all rocky and similar in size to Earth, with radii ranging from about 0.75 to 1.15 times that of our planet. Three of these planets (TRAPPIST-1e, f, and g) reside in the star's habitable zone, where conditions might allow for liquid water on their surfaces, making them prime candidates in the search for extraterrestrial life. The planets orbit very closely to their star, with periods ranging from 1.5 to 13 days, likely causing them to be tidally locked. This means one side of each planet always faces the star while the other side remains in darkness. The discovery was made using the transit method, which detects dimming of the star's light as planets pass in front of it. Follow-up studies with telescopes such as Hubble and Spitzer have provided further insights. The TRAPPIST-1 system is of significant interest for its potential habitability and the unique opportunity it offers to study Earth-sized exoplanets in detail. #trappist -1 #trappist #space #4k #astronomy #universe #edit #scary #nasa #viral #fyp #foryou #planet #habitablezone
