TRAPPIST-1 f
TRAPPIST-1 f
TRAPPIST-1 f is an exoplanet orbiting the star TRAPPIST-1, located about 39.5 light-years (12.1 pc) away from Solar System. Its discovery was publicly announced on 2017.
The host star TRAPPIST-1 has apparent magnitude of 18.8, with absolute magnitude of 18.4. It is 0.1 times more massive and 0.1 times bigger compared with our Sun. The surface temperature is 2560 with its spectral types of M8
In this planetary system, the extrasolar planet TRAPPIST-1 f orbits around the star TRAPPIST-1 every 9.2 days with its orbital distance of 0.04 AU ( 5550081.0 km)
(Projected orbit of TRAPPIST-1 f around its host star TRAPPIST-1)
The Star TRAPPIST-1 's habitable zone is located at the following distance
