What is Oort Cloud?

Oort Cloud is a huge spherical cloud of comets and dust that extends three light years from the Sun in all directions. The fact that the cloud is more spherical than in the shape of a disk distinguishes it from other collections of residues in the solar system, such as the asteroid and Kuiper belts. The ball is so great that its edge is closer to our closest star than the sun itself. The edges of the Oort cloud generally represent the limits of the gravitational influence of the Sun - Comet, which have lost too far from the edge, will be lost into space and become interstellar wandering.

It is assumed that almost every star has its own Oort Cloud, larger or smaller in size. Oort clouds certainly overlap and the Oort cloud of our Sun is likely to overlap with the Alpha Centauri cloud. When the clouds overlap to the extent that the edge of a strange cloud is surrounded by another star, the above -average comet frequency will be seen in the central regions of the solar system of this star.

oort cloud was first theorized in year 1950, when Jan Oort noted that there were no circular comets that indicate that they come from the outside of the solar system, that there is a strong tendency for comet to come to 50,000 AU (50,000 times more distance between the Earth and the Sun). This led to an oort cloud hypothesis, a cloud that cannot be observed in binoculars, because the comets that produce it are too small and far apart. It is estimated that there are probably trillion comets in the Oort cloud, with a combined mass of 100 times higher weight of the Earth. It is theorized that the Oort Cloud objects have indeed been formed relatively close to the sun, closer than Neptune's orbit, but were released into huge parabolic pathways when they were crushed by gravitational holes of huge planets like Jupiter.
