Sunset on TRAPPIST-1b, illustration. We are looking away from the setting Sun on the exoplanet TRAPPIST-1 b. What appear to be moons in the sky are in reality four of the outer planets in the system. The TRAPPIST-1 planets orbit so near one another they are easily visible from the surface of each. | |
