The Oort cloud (/ ɔːr t, ʊər t /), [1] sometimes called the Öpik–Oort cloud, [2] is theorized to be a vast cloud of icy planetesimals surrounding the Sun at distances ranging from 2,000 to 200,000 AU (0.03 to 3.2 light-years).
Scientists think the Oort Cloud is a giant spherical shell surrounding our solar system. It is like a big, thick-walled bubble made of icy pieces of space debris the sizes of mountains and sometimes larger. The Oort Cloud might contain billions, or even trillions, of objects.
In 1950, astronomer Jan Oort proposed that certain comets come from a vast, extremely distant spherical shell of icy bodies surrounding the solar system. This giant swarm of objects, now named the Oort Cloud, occupies space at a distance between 5,000 and 100,000 astronomical units.
The Oort cloud is a collection of comets, small km-scale icy (and perhaps rocky) left-overs from the process of solar system formation. It is a spherical collection of bodies orbiting the sun.
Oort cloud, immense, roughly spherical cloud of icy small bodies that are inferred to revolve around the Sun at distances typically more than 1,000 times that of the orbit of Neptune, the outermost known major planet. Named for the Dutch astronomer Jan Oort, who demonstrated its existence, the Oort.
The Oort cloud is a vast and enigmatic region of space located at the outermost edges of our Solar System. It’s home to long-period comets and trillions of icy objects. Unlock the mysteries of the Oort cloud with this article!
Oort Cloud. The distant Oort cloud marks the gravitational edge of the Solar System, in a vast region of undiscovered objects. The boundary between the Kuiper Belt and Oort cloud is less distinct.
The Oort Cloud is a theoretical spherical distribution of icy bodies surrounding our solar system. It contains trillions of objects ranging from small boulders to large planetesimals. Jan Oort proposed this concept in 1950 to explain the origins of long-period comets.
This giant swarm of objects, now named the Oort Cloud, occupies space at a distance between 5,000 and 100,000 astronomical units. No objects residing within the Oort Cloud have ever been directly observed. The outer extent of the Oort Cloud is where the Sun’s gravitational influence can be overpow-ered by that of other stars.
Beyond the fringes of the Kuiper belt is the Oort Cloud. Unlike the orbits of the planets and the Kuiper Belt, which are pretty flat like a disk, It's a giant spherical shell surrounding the sun, planets, and Kuiper Belt Objects. Like a big bubble with thick walls around our solar system.
