It's going very slow and looks like a comet.
So, if it is aliens:
They are disguising themselves.
Which implies that their technology is not that far away from ours. Otherwise, why disguise yourself? Why go so slowly?
The only nearby system that makes remote sense to have sent a slow object is the nearest one: Proxima Centauri, which happens to have an earthlike planet in the habitable zone, Proxima b
A fusion drive ship would have to have left Proxima b about 70-100 years ago, so around when our civilization would have been visible to them.
Earth is the closest neighbor to Proxima b, just as they are our closest neighbor. A civilization there would have been as interested in us as we are them.
A fusion drive ship would have accelerated for half the journey and decelerated for the other half, during which it is possible that a ship could have manouvered to enter the solar system on a path which would appear to arrive from the galactic center. They could have done this to obscure their origin.
The remnant heat of a fusion burn would be visible to JWST. However the only time it was scheduled to look towards Proxima they had "technical difficulties" and the data was "useless", which could be a sign of military censorship, or you could believe that earth's best astronomers built a telescope which can look at anything except our closest neighbors.
This is all speculation but it does narrow the range of outcomes. If it is aliens they
>Are close to us technologically, more advanced but not so far ahead that they have nothing to fear
>Have a reason to come here, perhaps they intend to colonize because Proxima is a red dwarf becoming less stable, with more frequent and extreme solar flares
Then there is the UAP thing. Could that be a directed energy weapon/device originating from 3i/Atlas?
It's fun to speculate, but JWST was scheduled to take pictures of 3i/Atlas today so we should have some good big ol' turd shaped rock pictures soon.
