TRAPPIST-1 h
Sign in to saveTRAPPIST-1h is an exoplanet orbiting around the ultra-cool dwarf star TRAPPIST-1, located away from Earth in the constellation Aquarius. It was one of four new exoplanets to be discovered orbiting the star in 2017 using observations from the Spitzer Space Telescope. In the following years, more studies were able to refine its physical parameters.

TRAPPIST-1h is an exoplanet orbiting around the ultra-cool dwarf star TRAPPIST-1, located away from Earth in the constellation Aquarius.

The outermost known planet in its system, it is roughly one third the mass of Earth, and about 76% as large. Its relatively low density indicates that it is likely water-rich, like several other planets in the system.
