A video explained what would happen if a star as massive as the Sun enters the Solar System. According to the video, this would trigger a series of catastrophic events that would eventually destroy Earth.

A video recently released by the YouTube channel What If explored the idea of a rogue star moving across space to enter Earth’s neighborhood. Once this happens, the star would first pass through a region filled with icy space rocks near the edges of the Solar System known as the Oort cloud.

Depending on the size of the star, its gravitational force would affect the movement of the space rocks and send them hurtling toward the inner regions of the Solar System. As explained in the video, this event could send hundreds of space rocks to hit Earth on a daily basis.

“The rogue star would make its way into the Oort cloud,” the narrator of the video explained. “At this point, it wouldn’t affect us directly, but it would send massive chunks of space rocks showering the Solar System. About 170 meteors, comets and asteroids would hit the Earth every day. That’s ten times more than what’s bombarding our planet right now.”

Unfortunately, getting pelted by meteors and asteroids every day won’t be the worst effect caused by the sudden appearance of a second sun in the Solar System. If a star as big as or even bigger than the Sun appears, it would most likely drag its own system composed of planets and moons.

During such an event, the orbits of the planets within the Solar System would be disrupted, which could cause them to crash into one another. If Earth manages to survive a direct collision with a planet or a moon, it would most likely get hit by asteroids or the huge chunks of debris that came from the massive cosmic objects that were already destroyed.

“If the rogue star had other planets and moons following it, our Solar System would turn into a galactic soup, with stars and planets being pulled out of their orbits,” the video stated. “Massive collisions would create a rippling effect, disrupting planetary orbits even more. Eventually, the Earth would be knocked out of its orbit too, if it wasn’t already destroyed by meteor storms and the remnants of other planets.”
