It is sent by aliens to probe uranus

The first is Clever and often incorrect.  The second is Wisdom and quite a bit more rational.

"It's never aliens, until it's proven to be." Matt from PBS Space Time.

The universe is littered with rocks and debris and 20Km isn't even the biggest rock in either our Kuiper Belt or the Asteroid Belt. The fact that this one rock is going "the wrong way" as evidence of anything suggests someone has a weak grasp of orbital dynamics and statistics.
The planets and most of the rocks in the solar system go the same direction because they all formed from the same gas cloud which obviously had to be spinning in just one direction... but once it coalesced into planets, moons and rocks, collisions and interactions with gravity from other bigger rocks, planets and moons means from time to time, some of those rocks will get turned around, or even just get flung out of the solar system entirely.
And if one of those rocks just happens to enter another planetary system, it's direction of motion will have NO relationship to that system's preferred rotation. In fact, even comets in OUR system, when tend to come in from Oort Cloud, don't always follow the preferred spin direction.
Sometimes a rock is just a rock.

i think there isnt a single interstellar object that wasnt suspected to be an alien-something at some point

Is it anal probe?
