Based upon scientific measurements, 31 Atlas had SLOWED DOWN,...SLIGHTLY, as of today, and displayed unusual behaviour that is un-typical of OTHER comets studied.....
1. Instead of gaining speed thru the gravity of the sun, it seemed to be able to slow itself down.
a. Most comets are merely made up of ice, and as it gets close to our sun due to gravity, the ice would melt and glows red, but 31 Atlas did not glow red, instead it turned brighter blue, which means either its composition is not made of ice, but of exotic materials that not only could absorb extreme heat, but REPEL extreme temperatures, for it to survive.
b. Most comets would leave a melted ice vapor trail at the rear, as it speeds towards the sun due to the sun's gravity. However, 31 Atlas instead of leaving such usual trails, it seemed to have EJECTED vapor TOWARDS the sun.....a sentient intelligent manoeuvre to SLOW DOWN?.....
Furthermore, it had showed signs of achieving Non-Gravitational Acceleration, which simply means it seemed to have intelligent sentient control onboard to SLOW DOWN that massive space object, that no other comets observed had done so before.
For simple example of speed and gravitational pull:-
i) Should a normal fighter jet at speeds of 2000km/hr, sees an armada of enemy jets in front, the pilot would turn tail and run.
However, at such speeds, he would have to fly several hundreds more km to the front, with a WIDE angle turn taking several minutes at high Gravitational Force which only brings him closer to the enemy jet armada.
ii) However, if he flew the F35 jet, upon receiving info from radar and sight, just by a twist of his his control stick and yoke, the plane can make a 180 degrees turn on the aircraft's own axis within 7 seconds.
As per Newton's laws on motion, the plane will still be thrown forward due to its speed, but that speed would decelerate within seconds to zero, and with his thrusters, he would be able to zoom away from the enemy jet armada in seconds.
2. Thus, what is 31 Atlas?
It is now beyond Humankind's view as it is moving behind the sun, which it will reappear sometime in December, for Earth based instruments to track and determine. However, there are still space based scientific instruments from other Nations, not just NASA, in Earth's and other planets orbits that can still track and observe this mysterious Nickel Alloy Manhattan building sized object.
As it had slowed down, does it intends to STAY within our Solar System orbit, or perhaps thru some yet to be discovered science and physics to slingshot using our Solar System's gravitational pull to move elsewhere in the Universe?
