Shortly after the discovery of TRAPPIST-1 and three of its planets was first announced in May 2016, scientists started to figure out a way to turn Kepler toward the system for observation.

This 2018 artist's concept shows what the TRAPPIST-1 planetary system may look like, based on available data about the planets' diameters, masses and distances from the host star (far left).

If you keep up with NASA at all, you'll know that they recently made a kind of huge discovery: Trappist-1, a solar system older than ours with seven Earth-sized planets. It's fine, I'm fine ...
