According to NASA, Google's machine learning algorithms found an eighth exoplanet in an extrasolar system known as Kepler-90, which means that our own solar system is now tied for the most known planets orbiting a single star. . Kepler-90, also designated 2MASS J18574403+4918185, is an F-type star located about 2,790 light-years (855 pc) from Earth in the constellation of Draco. Our solar system is tied for most number of planets around a single star, with the 2017 discovery of an eighth planet circling Kepler-90, a Sun-like star. . The planet, known as Kepler-90i, is one of two discovered by a powerful neural network sifting through NASA data. In a first for astronomy, scientists trained a neural network to sift through scads of data from a planet-hunting telescope, and it found a whole new world. What have we learned? Planets are very different. On this seemingly nice, blue planet, glass rains sideways. The similarities don't stop there.
