Astronomers have conducted computer simulations of the solar system’s future, revealing a new risk facing Earth: the gravitational tug of a passing star could cause another planet to collide with our planet or fling it into the sun or far away from it. The risk is estimated to be 0.2% over the next 5 billion years, with the most dangerous stars being those that come closest to the sun and move slowly. This new study highlights the vulnerability of our planet to planetary chaos.
Forecast for 6 months: In the next 6 months, astronomers will continue to study the effects of passing stars on the solar system, and the scientific community will engage in discussions about the potential risks and consequences of such events.
Forecast for 1 year: In the next year, researchers will likely conduct more simulations to refine their estimates of the risk of catastrophic collisions and develop strategies for mitigating these risks, if necessary.
Forecast for 5 years: In the next 5 years, the scientific community will continue to monitor the solar system for signs of gravitational perturbations caused by passing stars, and the risk of catastrophic collisions will be reassessed based on new data and simulations.
Forecast for 10 years: In the next 10 years, humanity may develop new technologies to protect against the effects of passing stars, such as advanced gravitational shields or planetary defense systems.
