Astronemers may be regretting their choice to downgrade Pluto's planetary status today after NASA announced the discovery of a solar system that rivals our own.
The Kepler space telescope is NASA's "planet-hunter". Back in 2014 it discovered Kepler 90, a sun-like star with 7 seven orbiting planets, 2500 light years from Earth.
Today NASA announced that with the help of Google machine learning they were able to discover an eighth planet, tying Kepler 90's system with ours for most number of planets.
Our @NASAKepler mission's search for new planets teamed with machine learning to discover another solar system with an 8th planet that is 2,500 light-years away.

The new planet dubbed Kepler-90i "is a sizzling hot, rocky planet." The smallest of he eight planets in it's system Kepler 90i orbits its star so closely its year only lasts 14 days. In fact all eight planets have a very compact orbital path that fits within the distance between Earth and the sun.
With 8 planets in Kepler-90, we’re now tied for first in the most planets around a star (we’d still be winning if Pluto were a planet…)— Bobak Ferdowsi (@tweetsoutloud) December 14, 2017
