Hello,

People on this planet earth have found asteroids circling around the sun in an ecliptic orbit.

For this to happen there must be a counter-weight, at least according to math/newton physics laws.

Now some believe that there must be a hidden planet that we have not found yet, causing these ecliptic orbits.

However what if there is no planet ? What if an object was there but is now gone ?

Possibilities:

1. It was a planet but got spong off and is lost in space.
2. It was a planet of another solar system that we almost collided with. Though perhaps less likely cause it might have pulled much more out of orbit.
3. It could have been a gigantic spaceship that jumped into space, stayed there for a while, got ****ed at the dinosaurs eating one of them and then decided to blow up the whole planet.

So one more time:

1. Spaceship visits our solar system.
2. Stays there for a while, long enough to pull asteroids into an ecliptic orbit.
3. Something bad happens which makes them decide to blow up earth with a projectile or maybe their visitation caused an asteroid to be pulled out of regular/normal orbit and collided with earth (maybe later after they gone).
4. Spaceship jumps home.

And we are left with unexplained ecliptic asteroids.

Enjoy the sci-fi,
Bye for now,
Skybuck.
