Suffering an impact from a traveling planet would result in the complete destruction of Earth. The fact that it only appears in the solar system also changed the orbits of all the planets.
Unlike Earth or the planets orbiting the Sun, there are currently billions of planets roaming the Milky Way galaxy and not tied to any host star.

However, one thing scientists are discussing is what happens when a wandering planet enters the solar system, even when approaching Earth. According to What If, a wandering planet has been discovered beyond the limits of the solar system.
What is a wandering planet?
Unlike the planets orbiting the solar system, rogue planet is a planet that moves freely between stars and does not orbit a host star.
At birth, gravity can cause planets to collide. The collision could cause the planet to deviate from its host star’s orbit, becoming a wandering planet.
In 2015, Canadian scientists published research indicating that a gaseous planet existed in the solar system more than 4 billion years ago, but there are indications that it is invaded by Jupiter. “rock out of orbit” after the collision, according to Science Alert.
In addition, the wandering planet also comes from stars that cannot burn, turning them into lone gas planet.

Scientists don’t know how many planets roam the Milky Way galaxy because these planets are difficult to observe because they don’t emit much light. However, the number is estimated in the billions, Newsweek said.
Undesirable scenario
In 2018, scientists discovered a wandering planet, just 20 light years from Earth, 13 times larger than Jupiter – which is currently the largest planet in the solar system (61.42 billion km2). Meanwhile, the area of the Earth is about 510 million square kilometers.
Scientists have proposed a scenario for whether wandering planets will enter the solar system, or even collide with Earth.
With an area thousands of times larger than Earth, a traveling planet can move at hundreds of kilometers per second. A direct collision would result in the complete destruction of the Earth.
However, scientists also say that the scale of the solar system is quite large. In the collisionless case, Wandering planets will also disrupt the orbits of all planets in the solar system. The planet’s gravity of over 770 billion square kilometers will make the orbit of the solar system even more elliptical.
At that time, the Earth will revolve around a narrow region of the solar system. Although humans can still live, orbiting close to the Sun makes summers very short and hot, in addition to winters extremely cold and long.

Earth could be entering the next ice age. Instead of global warming, humanity will worry “global cooling”.
However, in addition to hypothetical scenarios, scientists also mention the fact that there are many objects in space and the probability of a wandering planet threatening the Earth is not high.
“I estimate that over the next 1,000 years, the probability of the rogue planet hitting Earth, rather than Mars or Venus, is once in 2 trillion.”said Garrett Brown, an astrophysicist at the University of Toronto (Canada).
Michel Zemcov, an associate professor of physics at the Rochester Institute of Technology, said the fact that the solar system was able to exist stably for more than 4.5 billion years was a surprise, given the gravity and fields magnetic planets like Jupiter. was able to push other planets out of orbit, turning them into wandering planets.
