TRAPPIST-1b is a terrestrial, Earth-sized exoplanet orbiting around the ultra-cool dwarf star TRAPPIST-1, located 40.7 light-years (12.5 parsecs) away from Earth in the constellation of Aquarius. The planet was detected using the transit method , where a planet dims the host star's light as it passes in front of it.
TRAPPIST-1 TRAPPIST-1 is within the red circle in the constellation Aquarius. Observation data Epoch J2000 Equinox J2000 Constellation Aquarius Right ascension 23 h 06 m 29.368 s Declination −05° 02′ 29.04″ Apparent magnitude (V) 18.798 ± 0.082 Characteristics Evolutionary stage Main sequence Spectral type M8V Apparent magnitude (R) 16.466 ± 0.065 Apparent magnitude (I) 14.024 ± 0. ...
TRAPPIST-1c was observed with the transit method, which enabled scientists to calculate its radius. Transit-timing variations and computer simulations were able to determine the mass, density, and gravity of the planet. TRAPPIST-1c is the third-largest planet of the TRAPPIST-1 system, with a radius of 1.097 R 🜨.

Scientists have waited on pins and needles for more details about the TRAPPIST-1 solar system, a family of seven Earth-size planets discovered not too far away that could support life. Now the ...
TRAPPIST-1e, also designated as 2MASS J23062928-0502285 e, is a rocky, close-to-Earth-sized exoplanet orbiting within the habitable zone around the ultracool dwarf star TRAPPIST-1, located 40.7 light-years (12.5 parsecs; 385 trillion kilometers; 239 trillion miles) away from Earth in the constellation of Aquarius.
TRAPPIST-1d is a small exoplanet (about 40 percent the mass of the Earth), ... TRAPPIST-1b and c, are unchanged. But there’s a new third planet, which has taken the ...
TRAPPIST-1b and c receive the most light from the star and would be the warmest. TRAPPIST-1e, f and g all orbit in the habitable zone, the area where liquid water is most likely to be detected. But any of the planets could potentially harbor liquid water, depending on their compositions.
