TRAPPIST-1 Planets Could Hold 250 Times the Amount of Water as Earth’s Oceans

A new study estimates the masses of the seven Earth-like planets, which provides insights on what their atmospheres and surfaces may be like.

This chart shows artistic concepts of the seven planets of TRAPPIST-1. It also compares them with Earth, by providing their orbital periods, distances from their star, radii, masses, densities and surface gravity. | NASA/JPL-Caltech
