Can the star save us from extinction caused by the Sun? According to research yes

Unless humanity has gone through some kind of self-destruction through climate change or world wars, HEScientists point out that the Sun will become hot enough to ‘cook’ and destroy life on Earth within a few billion years.. A star could save us from this particular extinction event, according to a study published in the scientific journal Monthly Notices of the Royal Astronomical Society.

A group of researchers, in partnership with France’s University of Bordeaux and the Planetary Science Institute in Tucson, United States, suggested that a star could save the planet from the most intense solar events expected to occur billions of years from now. Now. . A total of 12,000 simulations were performed to understand what would happen if a star passed by Earth from approximately 15 billion kilometers away.

Researchers explain this ThisIn 0.28% of these simulations, the star pulled the Earth into a region that would not be as affected by the Sun. For example, in one of the tests the Earth’s orbit was ‘pulled’ beyond Pluto, a cooler region that could help us in case of heat; In another example, Our planet was sent to a place 2 billion light years away.

“I thought there would be more. It’s really not that easy to mess with the orbits of planets; a star really has to mess with another star to mess with its planets,” study author Sean Raymond of the University of Bordeaux said in a post on the website. If they do, floating planets could retain enough heat to keep liquid water on the surface. New Scientist.

star against extinction

In 92% of all simulations, the Solar System would remain intact despite the passage of this star, and in the full 0.28% it did not help save the planet. In some cases, the Earth was destroyed by collisions with the Moon or other cosmic bodies after being removed from the area where the Sun struck.

The study suggests that there is only a 1% chance that a star will actually pass by Earth in the next billion years; furthermore, the odds of the Earth moving to a stable position would be only 1 in 350. In other words, it can happen, but it will depend on many factors and a little bit of luck.

“[Para que as duas coisas aconteçam juntas] The odds of long-term life expectancy on Earth being saved by a passing star are one in 35,000. These are approximately the same odds as randomly drawing the ace of spades from two separate decks and also rolling a 10 with two dice. These are not the best odds,” adds Raymond.
