Context:

Scientists at NASA has discovered eighth planet circling Kepler-90, a Sun-like star which is 2545 light-years far from Earth. It was dubbed as Kepler-90i.

• The eight planet was discovered by applying Google’s machine-learning technology to data collected by NASA’s Kepler Space Telescope.
• The findings also establish the growing role that neural networks and other machine learning techniques could play in the hunt for more elusive planets outside our own solar neighborhood.
• With eight planets, Kepler-90 system equals our own solar system in terms of number of planets orbiting single star. Astronomers are yet to detect a system with more than eight planets. Kepler-90 star system is like a mini version of our solar system.

More about Kepler-90i:

• Kepler-90i is outermost and eighth planet in Kepler-90h system.
• It is around 30% larger than Earth.
• It is roughly the same distance from its star as Earth is from Sun.
• It orbits its star once every 14.4 days.
• It is thought to have an average surface temperature of 425 degrees Celsius.
