Scientists have discovered a new Earth-sized planet using data from the Transiting Exoplanet Survey Satellite (TESS), NASA said.

Footage shared by NASA, JPL-Caltech, Robert Hurt, and NASA’s Goddard Space Flight Center shows a visualization of the newly discovered world, named TOI 700 e.

NASA said the planet was around 95 percent the size of Earth and likely rocky. TOI 700 e is orbiting within the habitable zone of its star, meaning there could be liquid water its surface.

Scientists had previously discovered TOI 700 b, c, and d, all orbiting TOI 700, a small, cool dwarf star around 100 light-years away, in the southern constellation Dorado. TOI 700 b is about 90 percent the size of Earth. Credit: NASA/JPL-Caltech/Robert Hurt/NASA’s Goddard Space Flight Center via Storyful
