Can pass stars collide with our solar system and ultimately the Earth?
It is difficult to know if such a result is possible. Recently, researchers have discovered that the Milky Way may not fall into its nearby galaxies anytime soon. After turning into a red giant and expanding, our blue marble has been scheduled to be eaten by our sunshine for billions of years.
But researchers said in a recent study published in the Journal Icarus Thousands of computer simulations suggest that there is a possibility of a passing field star – a star that appears in the sky in the same area as the object being studied may cause more damage than previously thought.
“Our simulations suggest that isolated models of the solar system can underestimate the extent to which our giant planets will change in the future secular orbits. In addition, our planets and Pluto are significantly less stable than previously thought,” Nathan Kaib and Sean Raymond (a pair of astronomers) wrote in May. Kaib is from the Institute of Planetary Sciences in Iowa, and Raymond is from the University of Burdo, France.
The authors of the study said that over the next four billion years, past stars were the most likely trigger for instability.

Gravitational tugs can lead to unstable, fully stable objects, including Pluto: formerly the ninth planet of our solar system. Over the course of five hundred million years, stars can transform Pluto from a completely stable object to an object with chaotic gravitational interactions, thus disengaging it from orbit. While these changes occur within the time frame of Pluto, the odds of mercury are multiplied.
The risk of instability in the fifth planet of the solar system will increase by about 50% to 80%.
“We also found that the chances of losing Mars by collision or shooting are about 0.3%, and the chances of Earth involving planetary collisions or ejection are about 0.2%,” they wrote.
Kaib's previous work shows that three million years ago, a passing star changed the Earth's orbit.
Raymond told New Scientist. “These stars are actually always in the sun, cosmic.”

Nevertheless, these simulations illustrate Science News “None of these things are possible.”
Although, the media noted that the chance of collision with the Earth was 0.2% higher than previous studies found.
