What if a massive star invaded the Solar System?

The vast vast universe still has many mysteries yet to be discovered. And what if suddenly a huge, strange star invades our Solar System?

About 70,000 years ago, a red dwarf, dubbed the star of Scholz, crossed the Oort cloud, beginning to invade the Solar System. (The Oort Nebula cloud, which surrounds the Solar System with a diameter of 1 light-year, is the final boundary of the system.)

It is only 0.8 light-years from the Sun. Luckily, it suddenly reversed direction, not causing much trouble for the Sun. Currently, the researchers say there is another star, called Gliese 710, that is moving in the direction of the Solar System.

The Gliese 710 is about 60% the mass of our Sun and it travels throughout the galaxy at 52,000km / h. How long will that aggressor enter the Solar System and what will happen to humans?

When a star invades the Solar System, it causes chaos to a degree dependent on its size and orbit.

Previously, when Scholz's star passed through the Oort cloud near the Solar System, it did not affect the Earth much. Although, at that time, the first people on Earth were wiped out due to giant volcanic eruptions.

In fact, Scholz's star has changed the orbit of about 10% of comets and asteroids in the Solar System. It is also the cause of the appearance of giant space rocks in the Solar System.

At that time, an estimated 170 meteors, comets and asteroids attacked our planet every day, 10 times more than what happened today.

However, it is estimated that the Gliese 710 is bigger than the star in the past. According to experts, Gliese 710 is unlikely to reach the Solar System at least for 1.29 million years. But if that happens, it could shake the Earth.

In 1908, in Siberia, an asteroid crashed to Earth, the incident wiped out about 80,000 trees and blew away the windows of people's houses as far as 60km. At that time, if the incident occurred in New York, the entire city would be in the impacted area.

And if a star larger than the Sun enters the Oort cloud, it will disrupt the orbital cycles of every planet it passes through and the disruption will occur for millions of years. Some planets may even collide.

However, that is not the worst. If a big star were to follow its planet and moon, our Solar System would become extremely chaotic. Large collisions will create ripple effects, breaking the orbits of the planets.

Eventually, if the Earth survives to that point, it could be knocked off orbit.
