On Thursday, NASA announces the discovery of eighth in the Kepler-90 solar system, after reviewing data from the space agency’s Kepler Space Telescope. Kepler-90 is a Sun-like star and all of its eight planets are scrunched up in a distance, equal to the distance of the earth from the sun.

Orbit of planets in Kepler-90 solar system

The newly discovered planet Kepler-90i is a hot and rocky planet with an average temperature of 800 degrees Fahrenheit, therefore no chance of life on that planet. The planet complete it’s orbit in just 14.4 days while Mercury has the orbit of 88 days.

This Kepler-90 solar system is nearly 2500 light year away from us and is also set-up similar to our solar system. The smallest planet is located close to its star and the larger planet located away from it.

These are planet are being discovered under K2 mission, which aims for hunting planets outside our solar system. All the discoveries have been made possible by machine learning algorithm from Google.

This AI system spots the difference between patterns associated with the planets and the patterns of cosmos which are of other type and could be false positives. Which gives it 96 percent accuracy to find the real planets in Kepler’s data.

Paul Hertz, Astrophysics Division director at NASA Headquarters in Washington said that ” Kepler was the first ever telescope invented, capable of detecting a planet orbiting sun-like stars.” He also added, ” By applying Neural network an very advanced technology, we were able to discover this eighth planet in the distant solar system.”

Could Kepler-90 have more planet?

Kepler-90 solar system is said to be a rivalry to our own solar system as both of them have eight planets till now, but in future, it is possible that Kepler-90 has even more planets. Cause a vast area around Kepler-90 has not been searched for planets.

NASA is still searching for planets around the Kepler-90 Solar system. In 2012 the K2 mission was started and from then it has discovered near about 515 exoplanet candidates of which 184 were confirmed.
