Artificial intelligence helped NASA discover a planet system

It was Kepler-90 in the Draco constellation with eight planets.

Scientists from the US aerospace agency made a statement about discovering a planet system comparable to the Solar system in the number of planets rotating round the star. It was Kepler-90 in the Draco constellation with eight planets. This was reported by NASA with a publication of a video with computer modeling of the system.

The discovery was made with the help of analysis of data collected by the Kepler telescope conducted by artificial intelligence – Google’s neural net. About 35 thousand of records of natural signals from the environment of Kepler-90 were used.

Kepler-90 is located 2.5 thousand light-years (about 780 parsecs) from the Sun, and the estimated size of the 8th planet – Kepler-90 – is by 30% larger than that of the Earth.

The side-by-side comparison of the Solar system and the Kepler-90 planet system:

Moreover, NASA specifies that all planets in Kepler-90 are located closer to the star than the Solar system planets to the Sun, so it’s a bit too hot on the detected moon. The average temperature of its rocky surface is higher than 400 degrees Celcius, which is comparable to the temperature of the closest planet to the Sun – Mercury. A “year” on Kepler-90 lasts 14.4 of the earthday.

The farthest planet from Kepler-90 lies on about the same distance from the star as the Earth from the Sun.
