Are you discovering that objects move faster as they approach the sun? What to look for next: because the object has angular momentum, it’s going to miss the sun, but without an impact, its speed is only gradually going to slow down as it gets further and further away until its distance from the sun balances out, and then its going to start falling towards the sun again.

gradually going to slow down as it gets further and further away until its distance from the sun balances out, and then its going to start falling towards the sun again. -- All astronomers say its going too fast for the Sun to slow it down and is on course for a close approach to Mars [ I AU ] before it goes behind the Sun, after which its course will take it to Earth [ >2 AU ] followed by a close approach to Jupiter [ >I AU ] before it leaves our Solar System. This object is crossing the Solar System at a never before seen speed, entering in the plane of the ecliptic [ where all the planets reside ], doing a very close approach to 3 planets and passing distantly by a 4th. The odds of a random object 10.5 km in diameter entering the solar system are very very small; the odds of it passing so close to 4 planets at 60 km per second is vanishingly tiny - you'd need a ream of paper to write the number. Calling it a 'comet' is just a way of dismissing it, without bothering to learn more about what it actually may be.
