In 1803 the townspeople in Richmond, Virginia, were roused from their beds by a fire alarm and were able to view a very rich display between 1 and 3 o'clock. The meteors "seemed to fall from every point in the heavens, in such a manner as to resemble a shower of sky rockets."
"Long ago, a massive perturbation of orbits in the Oort Cloud, perhaps triggered by a passing star or a tiny black hole, sent millions of comets hurtling towards the sun. As they crossed the paths of the planets, some struck with the force of unimaginable explosions, gouging out craters hundreds of miles across and irrevocably altering the delicate balance of planetary orbits. Those that reached the sun were torn apart by its gravity, their icy bodies fractured into countless fragments that were flung back into the Oort Cloud in vast, elliptical trajectories. These icy shrapnel, a ghostly armada of cosmic debris, now returns. Over millennia, they will bombard the inner planets once more, a relentless storm of impacts that will reshape the face of Earth. New mountain ranges will rise from the shattered crust, while devastating earthquakes and volcanic eruptions will tear the land apart. The very air will be thick with dust and ash, blotting out the sun. This cosmic maelstrom will last for centuries, a period of unparalleled geological upheaval that will test the very limits of life's resilience."
The backside of the Moon.
It may be that the theoretical "ninth planet" is a tiny black hole. Invisible to astronomers but Stellar-mass black holes are typically in the range of 10 to 100 solar masses. If in orbit about our own Sun and within the Oort Cloud its orbit could be thousands of years.
