If Another big planet enter our solar system, what will happen

If another big planet entered our solar system, it would have a significant impact on the other planets and their orbits. The exact effects would depend on the size, mass, and trajectory of the new planet.

One possibility is that the new planet could collide with another planet or moon in the solar system. This would be a catastrophic event, with the potential to cause widespread destruction and extinction.

Another possibility is that the new planet could be captured by the sun's gravity and become a new member of the solar system. In this case, the new planet's gravity would interact with the gravity of the other planets, causing their orbits to change. This could lead to more extreme weather patterns, changes in climate, and other unpredictable effects.

Even if the new planet did not collide with another planet or moon, its gravity would still have an impact on the solar system. The new planet could disrupt the orbits of comets and asteroids, increasing the risk of impacts with Earth.

Overall, the entry of a new big planet into the solar system would be a major event with the potential to have a significant impact on the other planets and their inhabitants.

Here are some of the specific effects that could occur:

The planets' orbits could be disrupted, causing them to move closer to or further away from the sun. This could lead to changes in climate and weather patterns.
The moon's orbit could also be disrupted, causing tides to become more extreme.
The new planet could interact with the asteroid belt and Oort cloud, sending more comets and asteroids towards Earth.
The new planet could also capture moons or asteroids, creating new moons or dwarf planets in the solar system.
In the worst-case scenario, the new planet could collide with Earth or another planet in the solar system. This would be a catastrophic event with the potential to cause mass extinction.

It is important to note that the probability of such an event happening is very low.
