The Oort cloud.
However, technically the Oort cloud IS part of our Solar System.
See related link for more information.
The Oort Cloud of comets.
Oort cloud
The solar system formed from the gravitational collapse of a cloud of interstellar gas.
it was born from the interstellar cloud
The hypothetical sphere around the solar system is known as the Oort Cloud. It is a region of space theorized to contain icy objects and comets that extends far beyond the orbit of Pluto. The Oort Cloud is thought to be the source of long-period comets that occasionally enter the inner solar system.
This is the Kuiper Belt. It is located just beyond Pluto. There is also the Oort Cloud that surrounds the whole solar system.
That would be the "Oort Cloud" of comets.
well the belt of rocks and dust past pluto is called the Kupiter belt, where the suns magnetic field weakens and terminal shock occurs and hello pause, where the suns solar wind slows to sub sonic speeds
The Oort Cloud of comets.
Oort cloud
The solar system was previously a cloud of interstellar gas.
The Solar System formed from a cloud of gas, that collapsed.
I presume you are referring to the Oort cloud.
The Oort cloud. It's actually not specifically between the solar system and Proxima, it's more like the outer layer of the solar system.
Solar nebula.
Comets primarily originate from two regions of the solar system: the Kuiper Belt and the Oort Cloud. The Kuiper Belt is a disc-shaped region beyond Neptune, containing many icy bodies, while the Oort Cloud is a hypothetical, spherical shell of icy objects that surrounds the solar system at a much greater distance. When gravitational perturbations occur, these icy bodies can be nudged inward, leading to their appearance as comets.
The Oort Cloud is the answer.
