According to the team, the gravitational pull of our solar system's planets and passing stars do not have much of an effect on the Oort Cloud. The team's new model was plotted from "a viewpoint of ...

Here, we show that the detection of Borisov implies that interstellar objects outnumber Solar system objects in the Oort cloud, whereas the reverse is true near the Sun due to the stronger gravitat… ...

The solar system consists of eight planets, several dwarf planets, hundreds of moons, and billions of asteroids, comets and ...
