TRAPPIST-1 is a cool red dwarf star [c] with seven known exoplanets. It lies in the constellation Aquarius about 40.66 light-years away from Earth, and has a surface temperature of about 2,566 K (2,290 °C; 4,160 °F). Its radius is slightly larger than Jupiter and …

2024年10月28日 · 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, the proportions of the TRAPPIST-1 system look more like Jupiter and its moons. Credit: NASA/JPL-Caltech. Full resolution.

2018年2月20日 · Forty light-years away, seven Earth-size planets closely orbit a faint star called TRAPPIST-1. We now know more about this system than any other beyond our own.

2023年10月4日 · TRAPPIST-1 was the first system of transiting exoplanets to be discovered by the TRAPPIST project, back in 2016. At first, only three planets were identified, but...

2017年2月22日 · Spitzer, an infrared telescope that trails Earth as it orbits the sun, was well-suited for studying TRAPPIST-1 because the star glows brightest in infrared light, whose wavelengths are longer than the eye can see. In the fall of 2016, Spitzer observed TRAPPIST-1 nearly continuously for 500 hours.

2024年10月24日 · TRAPPIST-1 e is a terrestrial exoplanet that orbits a M-type star. Its mass is 0.692 Earths, it takes 6.1 days to complete one orbit of its star, and is 0.02925 AU from its star. Its discovery was announced in 2017.
