Conceptual image of an artist of the surface of the exoplanet TRAPPIST-1f. Of the seven exoplanets discovered in orbit around the ultracool dwarf star TRAPPIST-1, this may be the most suitable for life. It is similar in size to Earth, is a little colder than Earth’s temperature and is in the habitable zone of the star, which means that liquid water (and even oceans) may be on the surface. The proximity of the star gives the sky a salmon-colored tinge and the other planets are so close as to appear in the sky, just like our moon.
