The star now known as TRAPPIST-1 was discovered in 1999 by astronomer John Gizis and colleagues [17] during a survey of close-by ultra-cool dwarf stars. [18] [19] It appeared in sample C [17] [18] of the surveyed stars, which was obtained in June 1999. Publication of the discovery took place in 2000. [20]
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-1g, also designated as 2MASS J23062928-0502285 g and K2-112 g, is an exoplanet orbiting around the ultra-cool dwarf star TRAPPIST-1, located 40.7 light-years (12.5 parsecs) away from Earth in the constellation Aquarius.
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.
A Belgian-led team made the discovery using both space- and ground-based telescopes, spotting the planets as they passed in front of the red dwarf star known as TRAPPIST-1.
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-1f, also designated as 2MASS J23062928-0502285 f, is an exoplanet, likely rocky, [2] orbiting within the habitable zone [5] around the ultracool dwarf star TRAPPIST-1, located 40.7 light-years (12.5 parsecs) away from Earth in the constellation of Aquarius.
First exoplanet to be discovered orbiting a main-sequence star. [188] Prototype of the hot Jupiters. HR 8799 e: 1.17 +0.13 −0.11 [189] ← 9.6 +1.9 −1.8 [190] First exoplanet to be directly observed using optical interferometry. HR 8799 system is also the first directly imaged planetary system having multiple exoplanets. TRAPPIST-1: 1.16 ± ...
