Planet Nine - a giant planet at the edge of the solar system, which has been searched for in recent years may be the one responsible for the unusual tilt of the sun.
In January of this year (2016), astronomers Mike Brown and Konstantin Betgin of Caltech predicted the existence of a ninth planet at the edge of the solar system that affects the orbit of some of the dwarf planets at the edge of the solar system. It now also appears to be responsible for the sun's unusual tilt.
"Because planet nine is so large and has a tilted orbit compared to the rest of the planets, the solar system has no choice but to spin slowly," says Elizabeth Bailey, a Caltech graduate student and lead author of the study that informs the discovery.
All the planets orbit the sun in a more or less flat orbit with a difference of a few degrees from each other. On the other hand, the orbit of the ninth planet, which has not yet been discovered but whose orbit is calculated according to its influence on other bodies in the solar system, is tilted on its side in relation to the other planets in the solar system, giving the impression that the sun itself is tilted upwards at an angle. So far, no one has found a convincing explanation for this that might create such an effect. "It's a fundamental mystery, so it's hard to explain so people just don't talk about it," says Brown, a professor of planetary astronomy.
The discovery of evidence that a yet-to-be-observed planet is 10 times heavier and larger than Earth and orbits 20 times farther than Neptune-Rahab is changing physics. According to the discoverers' calculation, this planet is inclined about 30 degrees above the plane of the other planets, affecting a large population of objects in the Kuiper Belt, and thus Brown and Tigin began to suspect that such a planet existed there in the first place.
"The Ninth Planet continues to amaze us. Every time we look, we will continue to discover an age-old mystery solved by the ninth planet." The research findings have been accepted for publication in the upcoming issue of the Astrophysical Journal, and it was presented at the 48th annual meeting of the American Astronomical Society for Planetary Sciences, held jointly in Pasadena, California, together with the 11th European Congress of Planetary Sciences.
"The inclination of the plane of the solar system's orbit has long confused astronomers because of the way the planets formed: when a swirling cloud collapsed into a disk, which then collapsed into objects surrounding the central star."
"The angular momentum of planet nine has an unusual effect on the solar system due to its location and size. The angular momentum of a planet is equal to the mass of the object times the distance from the Sun. This is consistent with the force the planet exerts on the spin of the overall system. Since the other planets in the solar system orbit it in a flat plane, their angular momentum works to keep the entire disk spinning smoothly."
"The unusual orbit of Planet Nine, however, continues to shift the systems for billions of years. "Mathematically, given the approximate size and distance of Planet Nine, a six-degree tilt is a perfect fit," says Brown.
The next question, then, is how did Planet Nine arrive at its unique orbit? Batygin estimates that the planet may have been thrown by the gas giant Jupiter or may have been affected by the gravitational pull of other yet-to-be-discovered powerful bodies in the solar system's stormy past.
For now, Brown and Batygin continue to work with colleagues around the world looking for signs in the night sky of the planet they saw in January. That search, Brown says, could take three years or more.

It means the rotation axis of the sun. It's just like saying that the earth has a tilt of about 23 degrees.
Think of the origin of the solar system as a giant cloud of particles. On the one hand, all the particles have an attraction to the center of the cloud, and on the other hand, there is a mutual influence between nearby particles. The result is that you can look at the cloud as a solid body, and as a solid body - it has a single axis of rotation. Even if we ignore this behavior, the angular momentum of each particle is considered - if we add (average if you will) all the values then we will get a single value at the end. And the only value is a vector with direction and strength.
Now - think that there are planets in the same plane, and a single planet in a different plane. The mutual influence of this system will result in positioning in a single plane, slightly different from the original plane.
2 questions... and sorry in advance for the ignorance:
1. I didn't understand what the strange inclination of the sun is? She is a ball. So how is a tendency possible?
2. How is it that all the planets revolve around the sun more or less in the same plane?
Thank you for honest answers
Thanks, now I understand.
The angular momentum is the product of the planet's distance from the Sun times the star's mass
and at its tangential speed
The angular momentum is the product of the planet's distance from the Sun times the star's mass
"The angular momentum of a planet is equal to the mass of the object times the distance from the Sun." – new physics?????? (I give up the Hebrew). Ah, I understood from Haim P's comment that the original intention of the sentence was probably to explain the effect of the new planet on the oscillation of the sun's center of mass, and this oscillation affects the inclination of the sun's axis of rotation. So in the end I probably understood.
It seems to me that the things are written in a way that is not clear enough. I will try to explain:
Each body orbiting another body actually creates two bodies orbiting their common center of gravity. Thus, the Earth and the Sun also revolve around their common center of gravity. And where is the center of gravity? We will divide the distance between them in proportion to their mass. (The Sun is 300,000 times more massive than the Earth) Then we will find that their common center of gravity is contained within the Sun. So the sun oscillates slightly due to the rotation of the earth.
In contrast, the common center of gravity of Sun-Zedek is at a distance of 750,000 km from the center of the Sun. That is, roughly the size of its radius. Jupiter is much more influential and causes the sun to really fluctuate.
The article talks about a star 10 times larger than Earth, and is at a huge distance. 20 times Neptune = 5 billion km. That is, about 100 billion km. The Sun is about 30,000 times more massive. We received a fluctuation of 3 million km. which is about twice the diameter of the sun. This is a real hit!
Add to that the fact that it rotates the sun at an angle of 30 degrees to the plane of the Melka (this is the plane that contains all the orbits of the planets orbiting the Sun) - and we got a rather unusual oscillation: the oscillation deviates from the plane of the Melka.
In fact, everything I said was "reverse engineered". The wobble (oscillation) of the sun has been detected, and the explanation for this wobble is that invisible planet.
Hope I helped clarify.
