Are there planets in the universe that are not bound by stars?

Do you know? A planet is a celestial body that does not emit light and orbits a star. Its rotation is often in the same direction as the rotation of the star it orbits.

Generally speaking, planets need to have a certain mass, and the mass of the planet must be large enough to be nearly spherical, and it cannot undergo nuclear fusion reactions like stars.

So your words are against the law in the first place.

The result is no.

It's not called a planet! Whatever it's called, there may be such a thing. But because it doesn't emit light (if it shines, it's a star), you can't see it. So there is no information.

It should be said that there is no such thing, you are talking about the constant system, which is not much in the universe, that is to say, the number of structures such as the sun and stars in the universe is very insignificant.

LZ means a celestial body that can roam freely between the stars, but there is no such thing.

But there is such a particle, in the vast universe, there is a kind of cold dark matter particle, which neither emits light nor rarely interacts with any matter. For 15 billion years, it has been coming to Earth endlessly, penetrating through anything from thick rocks, walls of thousands of homes to even our human body.

Possibly, but not less, in the solar system, if the sun is suddenly removed by humans, then the earth will become a single planet.

1.Mercury. 2.Venus.

Correct answer: Venus.

Venus is known as the sister star of the Earth, because it has many characteristics very similar to the Earth, and is the only planet in the solar system that does not have any magnetic field. Among the eight planets in the Sun's matronomic system, Venus has the closest orbit to the circular Changqing Bridge, and it is also the planet with the smallest eccentricity.

There are such outliers in the universe that do not belong to any galaxy and are called wandering stars:

1. When two galaxies meet, due to the strong gravitational pull of the other galaxy, some stars will be thrown out of their own galaxy and become "wandering stars" in the universe.

The process of two galaxies meeting will take millions of years to end, perhaps merging into a new stable galaxy; Perhaps the two galaxies were evenly matched, each changing its direction and speed of flight, and some of the stars were thrown out of their own system:

2. How to make a star speed more than 283km s (the fourth cosmic velocity to escape the Milky Way), more than 600 high-speed stars that have broken away from the Milky Way have been observed, and if there is no influence of extragalactic galaxies, there are 2 other stars in this galaxy that can achieve such high speeds:

In one case, when a pair of binary stars orbiting each other are captured by the gravitational pull of a black hole, one of the stars falls into the black hole in a spiral, and its companion star is thrown out at a great speed, at which point the accelerated acceleration may leave the home galaxy.

On the other hand, if a large galactic black hole (located at the center of the local galaxy) traps a small black hole (e.g., a stellar black hole) in the local galaxy, any star that is close to the small black hole may also be thrown out at an accelerated pace.

Escape from the stars of the Milky Way at high speed.

Stars never revolve around planets. If this happens, it would be contrary to the laws of the universe, which is that planets revolve around stars because the gravitational pull of stars is greater than that of planets.

No, because the definition of stars and planets is a primary and secondary relationship, stars are planets with relatively large masses, and planets are planets with low masses, so that the positions of stars and planets are always fixed.

No, because the planets rotate in the same direction, in the solar system. Although the rotation directions of Venus and Celestia are different, the rotation directions of the eight planets are the same.

No, in a galaxy, stars occupy more than 90 percent of the weight of the galaxy, and the greater the weight, the greater the gravitational pull.

It is possible that there is a system of ten stars in the universe. In general, there are most binary star systems, followed by single star systems, and there are few no stars or many stars. There is an almost infinite number of star systems in the universe.

If a star system contains too many stars, it will be unstable, it can be expelled due to gravitational effects, and the stars inside will collide with each other. The probability of a decile star system, if it exists, is very unlikely.

Of course, according to scientists' research, it has been found that there are between 1,000 and 4,000 star systems in the Milky Way.

In the universe, the positions of galaxies are constantly moving, according to Newton's law of gravitation.

The distances of galaxies are not stationary, on the contrary, the distances between galaxies are still expanding. At present, it is theorized that the universe is formed by the expansion of a singularity**, and the universe is still expanding at an accelerated pace, and the distance between galaxies is also expanding. This conclusion can be drawn from the redshift of the galactic spectrum.

It stands to reason that there is none, motion is absolute, the universe is full of gravitational and repulsive forces, celestial bodies will definitely move, and the whole universe is also in constant motion.

Galaxies may be rotating, but they are also moving in the same direction, because the planet will rub the heat if it rotates.
