A new, Earth-sized planet has been discovered only 90 light-years away from us. In astronomical terms, that’s right next door. What’s more, it might be capable of supporting life.
Named LP 791-18d, astronomers detected the exoplanet through ground- and space-based observations by NASA’s Transiting Exoplanet Survey Satellite (TESS) and its now-retired Spitzer Space Telescope.

The gravitational pull of other planets in the system causes these orbits.
