It has been suggested that comets originate in the Oort cloud and then travel in long elliptical orbits around the Sun.
I presume you are referring to the Oort cloud.
A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.
The Oort Cloud is the answer.
It is sometimes called the Solar nebula.
The Oort 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.
The sun formed from a large cloud of gas and dust in space about 4.6 billion years ago. As gravity caused the cloud to collapse, it heated up and formed the sun at the center, while the remaining material in the cloud eventually formed the planets in the solar system.
No, the Oort Cloud does not have rings. The Oort Cloud is a vast region of space beyond the outer planets in our solar system where comets are believed to originate from. It consists of icy objects and debris left over from the formation of the solar system, but does not have ring structures like those found around planets.

The Solar System formed from a cloud of gas, that collapsed.
The solar system was previously a cloud of interstellar gas.
The sun. Without the sun, there would have been no Solar system, just a bit of dust cloud floating around.
I presume you are referring to the Oort cloud.
that is called the Oort cloud and that's where comets come from.
Solar nebula.
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.
