Rocky Exoplanet TRAPPIST-1 c (Artist Concept)
Illustrated in the background is TRAPPIST-1 b, the innermost planet in the TRAPPIST-1 system. TRAPPIST-1 b is also rocky and appears to have no substantial atmosphere.
The star, TRAPPIST-1, is an ultracool red dwarf (M dwarf) with a temperature of only 2,550 kelvins (about 4,150 degrees Fahrenheit) and a mass just 0.09 times the mass of the Sun.
This illustration is based on new data gathered by Webb’s Mid-Infrared Instrument (MIRI) as well as previous observations
from other ground- and space-based telescopes. Webb has not captured any images of the planet.Relevante Artikel
