C/2014 UN271 Bernardinelli-Bernstein - A giant icy visitor from the edge of our solar system is on its way. Thought to be a rare long-period comet that swings into the inner Solar System from the distant Oort Cloud. Astronomers estimate this comet takes roughly three to five million years to make one complete orbit of the sun.

I don’t believe there is a (distance) limit on gravity. So the Sun’s gravity carries way more then 1 ly. But the inverse sq rule is a hard master.

Could the strange orbits of small, distant objects in our solar system lead us to a big discovery? Planetary astronomer Mike Brown proposes the existence of a new, giant planet lurking in the far reaches of our solar system -- and shows us how traces of its presence might already be staring us in the face.
