SOLAR SYSTEM

Detailed explanation-1: -The Oort Cloud lies far beyond Pluto and the most distant edges of the Kuiper Belt. While the planets of our solar system orbit in a flat plane, the Oort Cloud is believed to be a giant spherical shell surrounding the Sun, planets and Kuiper Belt Objects.

Detailed explanation-2: -The Oort Cloud is the most distant region of our solar system. Even the nearest objects in the Oort Cloud are thought to be many times farther from the Sun than the outer reaches of the Kuiper Belt.

Detailed explanation-3: -The Oort cloud is a shell of icy bodies that surrounds the solar system. It begins beyond the Kuiper Belt and even beyond the influence of the sun’s magnetic field, technically in interstellar space. There may be billions, or even trillions, of objects in it, and some are so large that they count as dwarf planets.

Detailed explanation-4: -The outer limit of the Oort cloud defines the cosmographic boundary of the Solar System and the extent of the Sun’s Hill sphere. The outer Oort cloud is only loosely bound to the Solar System, and thus is easily affected by the gravitational pull both of passing stars and of the Milky Way itself.

Detailed explanation-5: -The Cloud is thought to be comprised of two regions – a spherical outer Oort Cloud of 20, 000 – 50, 000 AU (0.32 – 0.79 ly), and disc-shaped inner Oort (or Hills) Cloud of 2, 000 – 20, 000 AU (0.03 – 0.32 ly).
