Will the moons of the wandering planets escape?

Since it is a wandering, it means that it does not belong to that star system and is floating in the universe. If it no longer exists in a certain system, it cannot be called an escape. Of course, if it is a celestial system at the level of escaping the galaxy, it is theoretically possible, but it is not easy to be thrown out of the galaxy.

Will they be captured together?

Yes, but capturing is rare, and if we follow the simplified model of our high school physics class, it is almost impossible to capture a celestial body. Only a celestial body that is very close to a mass far greater than it can convert a part of the kinetic energy of revolution into the kinetic energy of rotation can escape the parabola or hyperbolic orbit and be captured. In general, the mass of the captured object must be much smaller than that of another celestial body, such as the moons of Mars, Jupiter, and Saturn, which is really negligible in comparison to the planets.

Will it hit the earth?

Theoretically, yes, but the probability is too small. It's hard to get planets to wander, let alone travel through the vast interstellar space to enter the solar system and then enter a specific orbit to hit the Earth. Without going into other words, I've been thinking about the last step, and I've been wondering if I could design a little game that simulates a god who wants to destroy the Earth through a comet impact.

But what's so rare about hitting the Earth? First, the Earth moves, and it's still fast, 30 kilometers per second. On the other hand, the gravitational pull of the sun can accelerate the speed of the comet, and the gravitational pull of other celestial bodies can perturbate the comet's orbit, which is really unthinkable if you want to simulate the real solar system (so in order to reduce the difficulty, the comet should be given a little braking ability).

What happens when a wandering planet hits Earth?

Wandering planets (i.e., planets outside the solar system that do not have a host star), wandering black holes, and wandering stars will not hit the Earth for a number of reasons:

1. If they want to enter the solar system, they must have a smaller mass than the sun to be attracted to the sun, otherwise they will attract the sun (excluding the black hole).

2. After it is attracted by the sun, it is hovering on the edge at best, and if it enters the vicinity of the earth's orbit, it will definitely form a double galaxy with the sun, and will not crash into the earth (excluding the planets).

3. Even if it had a purpose (pronounced de) to destroy the earth, it would not hit the earth, because its mass was greater than that of the earth, and the earth would only crash into it.

4. Even if it crashes into the earth, it will not produce a shock wave, because it is larger than the earth and will only swallow the entire earth.

5. If you want this star to be smaller than the Earth, it is not enough to blow the Earth to pieces and turn it into a white dwarf, it must become a neutron star.

6. If it is a neutron star, then its mass must be greater than that of the Sun, and it does not meet the conditions of Article 1!

So don't worry, we're safe. But it is possible that an asteroid in the solar system will hit the Earth.

I don't know about this, but I heard that in a few hundred million years, the Tenga Galaxy will hit the Milky Way.

What happens when a wandering planet hits Earth?

To search for these wanderers, astronomers point telescopes at an area around the core of the Milky Way, called:

Galactic Nuclear Sphere". Using the gravitational microlensing effect, scientists have succeeded in finding 10 wandering planets with the mass of Jupiter for the first time. Subsequently, scientists estimated the total number of such wandering planets in the Milky Way based on detection efficiency, probability of microlensing events, and the probability of microlensing events for stars and planets.

The end result is about 400 billion. This number is far more than the number of main-sequence stars in the Milky Way. That's almost twice as many as the entire galaxy in the galaxy.

With so many planets, the probability of a natural impact on the Earth increases considerably. However, the wandering planets we have observed are quite far from the Earth, so at the moment we do not have to worry about the moons of the wandering planets hitting the Earth.

It's enough for you to wander all your life, and you'll be on your own!

Theoretically, yes, the satellite may leave the orbit due to perturbation during the movement, after which the orbital parameters will change, and theoretically it may collide with any planet.

However, now, after billions of years of gravitational interaction, the orbits of relatively large celestial bodies have reached resonance, which means that they are relatively stable with each other. It would be inconceivable for a satellite to hit the Earth without a huge gravitational perturbation (such as a star entering the orbit of Neptune).

It is necessary to add that due to the tidal action, the rotation energy of the earth is constantly converted into the gravitational potential energy of the moon, and it has been written in the popular science fingerchain article that the moon will escape in about 1 billion years.
