NASA’s exoplanet excursions

Take a guided journey through the amazing TRAPPIST-1 star system, known to be the home of 7 Earth-size exoplanets orbiting a star that is only a little larger than Jupiter.

This immersive virtual reality (VR) experience is based on the best current understanding of what these worlds could be like given their sizes, densities, and proximity to their star.

While the planetary images are artistic extrapolations, the relative sizes and positions are all portrayed accurately. Credit: Communications and Education group at Caltech/IPAC
