Neptune, the most distant planet in the solar system, could cause the destruction of the entire solar system, including Earth, if it was attracted by a passing star. But how can this be? I understand.
Our solar system is a perfectly balanced cosmic entity that supports our Sun with eight planets and one dwarf planet, Pluto. However, this gravitationally stable system has managed to remain so because various planets play a significant role in keeping it that way. For example, Jupiter, the largest planet, protects the inner ring from asteroids and meteors, and Mercury rotates at such a high speed that it constantly opposes the Sun’s gravitational pull to keep it in its orbit. But the planet that can affect the solar system the most is the farthest planet, Neptune. And not because its gravitational attraction affects the other planets, but because it is the most vulnerable planet in this system.
A transiting star can seal Neptune’s fate
Now, if Neptune suddenly disappeared from our solar system, not much would change. Pluto will likely face a changed orbit, and Uranus may shift its orbit a bit closer to Saturn, but the rest of the planets are too far away to even notice the disappearance. Even on Earth, probably the only people who would notice this are NASA astronomers and other scientists who study it, since Neptune is the only planet not visible to the naked eye.
However, if circumstances were slightly different, Neptune’s disappearance could throw the entire solar system into chaos. The solar system is not an isolated structure. It is part of the Milky Way galaxy, which is full of stars, planets, black holes, asteroids, meteors, gas and dust. And all of this is in constant motion. So, in a hypothetical situation, if our solar system were to hit another star, Neptune would be the first to know about it. According to a report by New Scientist, if the star knocks Neptune out of its orbit, the snowball effect could cause major instability in our solar system.
Neptune may be the first to shift, but given how powerful a star’s gravitational pull is, its impact will be felt all the way to the Sun’s core. And as each planet moves and shifts its orbit, the stability of the entire solar system is disrupted. What makes this truly horrifying are two considerations. First, the transiting star does not need to be as large as the Sun to cause this chaos. And second, we might not even be able to see it, since the star wouldn’t need to get too close to the solar system either.
