8 for Kepler-90

For the first time, eight planets have been found orbiting a distant star, Kepler-90, 2,545 light-years from Earth in the Draco constellation, NASA announced Thursday. It is the first star known to support as many planets as are orbiting our own sun, and researchers believe that this is the first of many to come.

Researchers had known that seven planets were orbiting the star. But Google Artificial Intelligence — which enables computers to “learn” — looked at archival data obtained by NASA’s planet-hunting Kepler telescope and uncovered the eighth planet.
