NASA has found a planet on which the seasons change every day

NASA astronomers have found traces of an exoplanet located in a "staggering" orbit in the Kepler telescope data, which is why the weather conditions on it are even more unstable than on Earth.
Astronomers were stunned when they found a planet, the tilt of its axis of rotation can vary by as much as 30 degrees for 11 years, which leads to a fast and erratic change of seasons. The discovered planet was named Kepler-413b.
"Imagine life on a planet where the seasons change at an incredible speed. In the evening, you will not know what to wear tomorrow - shorts or a coat," said one NASA expert. In contrast to Kepler-413b, the precession of the earth's axis is 23.5 degrees for 26,000 years.
Kepler 413-b is located at a distance of 2300 light years from Earth in the constellation Cygnus. Moving in its orbit, the planet approaches the central star of the system every 66 days.The planet rotates around a double star and staggers because its orbital plane is inclined 2.5 degrees relative to the orbital plane of the star pair.
As seen from Earth, the planet moves up and down continuously. Astronomers still can not explain why this planet behaves so strangely. They also believe that there may be other planetary bodies with a tilted orbit in the system. Or perhaps there is a third star nearby, which visually seems to be a satellite, but in fact it can be gravitationally attached to the system and influence the planet.
Even without taking into account the speed of the change of seasons, Kepler-413b is too warm for the appearance of life in the form in which we know it. Due to the fact that it rotates too close to the stars, the temperature on the surface of the planet is too high for the existence of liquid water, which makes it uninhabitable.
Like Neptune, a gas giant with a mass that is about 65 times the mass of the Earth, it does not have a solid surface on which to stand, writes in the latest issue of Mail Online.
Scientists plan to continue to study the unusual planet in the future, but according to their calculations, the next time the planet will appear in the field of view of the Kepler telescope no earlier than 2020.
