Around 50 billion maverick planets are wandering the Milky Way with no host star to the clutch. They don't radiate any light of their own and that makes them hard to spot.
The last time a wanderer planetoid the size of Mars crashed into Earth, it dispersed our planet's young outside layer into space, where gravity stuck those particles into what we currently call the Moon. This time, it would be all damnation and brimstone without any survivors left.
Also, here's a course of events showing how things separate... An obscure item would show up in the sky. It wouldn't occur out of the blue, no. We'd realize something was coming. We'd see the planet gradually become larger until one day it was pretty much as large as the Moon.
It appeared as though everything was unfurling at a somewhat lethargic speed, yet... that is simply because of the gigantic distances included. Out there in space, the maverick planet would surge towards us at the speed of 11 km/s (7 mi/s).
At the point when the excluded space interloper came into the Moon's circle, awful things would begin to occur. The gravitational draw of the outsider planet would make the tides on Earth multiple times bigger than they are present. Floods would erupt in a frenzy along with the coast's urban areas.
Furthermore, still, the megatsunamis are on their way. The gravity of the two planets pulling themselves towards one another would accelerate the interaction.
The approaching planet would hit a speed of 60 km/s (37 mi/s). Megatsunamis would plot their direction across the seas with this would come lightning storms, in addition to typhoons and twisters so enormous they wouldn't have a number on the classification scale.
If you didn't book yourself a get-away onboard a spaceship that would take you to space, your experience on this planet would be running out.
The maverick planet enters the Earth's climate. If you hadn't effectively been killed by the lightning, storms, flooding, tremors, or volcanoes, you'd see the rough intruder filling the sky above you.
The air of the two planets would be packed together and shine splendidly. It would get so hot that everything on the earth that was going to get hit would immediately disintegrate. For the remainder of the Earth, the ground would turn out to be burning magma. The impact would cause grating between the two planets.
A huge number of huge loads of superheated rock would send a mass of fire every which way. While the damnation spread across the Earth's surface, the planet's inward center dissolved it from back to front.
This would have one major result: the Earth would implode in on itself. The conclusion of the age. On the off chance that you figured out how to move away in a spaceship, you'd see the monstrous leftovers of the two planets slung into various circles.
Some of them would hit different planets. Others would be wiped out of the Solar System. Anything that remained would frame another space rock belt surrounding the Sun.
None of this would imply that intelligent life existed on Earth in the past. However, you can rest assured that this will never happen...Doubtlessly not.
