Q:

Where did comets that are now in the Oort cloud originally form?

A:

Quick Answer

Oort comets were formed in a few locations, including distances as far as Neptune, Jupiter, Saturn or Uranus's orbits. These comets are affected by the passing stars, and that sends some of them into the inner solar system.

Full Answer

Oort cloud comets likely formed around 4.6 billion years ago near where Saturn and Uranus are at the present time. Those comets were then deflected outward, according to Astronomy Notes, which caused them to be ejected out of the solar system or destroyed when traveling too close to Jupiter or to head into the Kuiper Belt if they were formed near Neptune's current orbit.

To understand the creation of the comets in the Oort Cloud, a person must know what the Oort Cloud is. The Oort Cloud is a large, spherical cloud. It has a radius between 50,000 and 100,000 A.U., and it is filled with billions or even trillions of comets.

People learning about the Oort Cloud should be aware that it has never been observed directly. Its existence is only inferred, which means that scientists believe it exists due to evidence and despite the fact that it has never been seen. Scientists determined its existence through the observation of long period comets, which have elliptical orbits.
