If it’s an alien (unlikely), i don’t see it going to earth. We’re too busy probing the grays that landed here in the 40’s and 50’s.

If it is coming to Earth, it is going to have to put on the brakes with some major propulsion. So far, it is still going at full speed. It is just a large comet or asteroid booking it through our solar system. It will be gone soon.

I don't make the rules, I just posted them for entertainment.
When at perihelion, more thrust will create a wider arc.
Less thrust will create a narrower arc.
Right?
So a small adjustment can significantly vary trajectory.
If hit the brakes enough, this thing can orbit the sun until it's on a direct path to earth.
Facts, not speculation.
Speculation if if it will or not.

I do not know.
Neither do any of you.

In a couple days it comes out from behind the sun.
Then we'll know if the trajectory changed.
If it changes, then ETs.
If not, then we still don't know!

Just out of curiosity, how many of you asked someone about this thing?
And how many knew what you were talking about?
Believe it or not, I talk about this a bit. :)
And nobody has heard of it.
That's kinda odd, right?
No matter what you think, we probably all agree this thing is COOL!!
And nobody knows about it.

Yeah because they don't know if it's going to break apart and hit earth or not. The mass panic from this would be... AWESOME !!

I hope I can one day be so certain about something I can't possibly know enough about to have any confidence in the accuracy of my statements.

It must be very reassuring

Or in other words, the difference between a duck is that one leg is the same.

When a comet gets close to the sun, solar radiation heats its icy nucleus. Volatile ices, like carbon dioxide, carbon monoxide or water, sublimate directly into gas, carrying away dust and small rocks. Smaller objects have a larger surface area per unit mass, making them more vulnerable to excess heating and further mass loss. This process can cause the comet to break apart if the mix of ice and dust cannot withstand the resulting thermal stress.
The jets of sublimated gas are not distributed evenly across the comet’s surface and act like thrusters, spinning up the nucleus. Fast rotation could also break up the comet as inferred for comet 332P/Ikeya-Murakami, whose rapid spin likely led to its fragmentation (see discussion here). Breakup from gravitational tides was demonstrated in 1994, when the fragments of comet Shoemaker-Levy 9, torn apart by Jupiter’s gravity, crashed into the planet (see discussion here).
