Artistic conceptual image of the surface of the exoplanet TRAPPIST-1f. Of the seven exoplanets discovered in the orbit of the ultracool dwarf star TRAPPIST-1, this one is perhaps the most suitable for life. It is similar in size to Earth, slightly colder than Earth’s temperature, and is located in the star’s life zone, meaning there could be running water (and even oceans) on the surface. The proximity of the star to the sky gives a shade of salmon, and the other planets are so close that they appear in the sky, much like our own moon.
