It was named for the Dutch astronomer, Jan Oort, though it was first hypothesized by Ernst Opik in 1932. Oort refined and re-introduced the idea in 1950.
The Oort cloud is spherical cloud of or shell comets nearly a light-year from the Sun. Comets are disturbed from this cloud by gravitational attraction and other factors and pass into the area occupied by the inner planets (Earth for example). Scientists then can observe these transient bodies to determine the composition of material in the Oort cloud.
The Oort Cloud is a region of space surrounding our solar system that is believed to contain trillions of icy objects, such as comets, extending out to about 1 light year from the Sun. It is thought to be the source of long-period comets that occasionally enter the inner solar system.
This icy cloud is known as the Oort Cloud and is located about 1 to 3 light-years away from the Sun. It is believed to be the source of long-period comets that occasionally enter the inner solar system. The Oort Cloud is a remnant of the early solar system and holds valuable clues about its formation.
The Oort cloud is a region of space surrounding the solar system that is composed of icy objects. It does not emit light itself, so it does not have a specific color.
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 correct spelling is the Oort Cloud of comets that is proposed to lie at the fringe of the solar system. It is named for Dutch astronomer Jan Oort (1900-1992).
The outer Oort cloud. (The inner Oort cloud is believed to be disk-shaped.)

The comets come from the Oort Cloud named after Jan Oort who suggested in 1950 that they originated from a common location in the Solar System.
It's called the Oort Cloud, named for a scientist named Oort who first theorized about it. It is a vast depository of stuff left over from the formation of our Solar System over 4 billion years ago. It's where comets come from.

Sedna is not located in the Oort Cloud. It is a trans-Neptunian object with a highly elliptical orbit that takes it far from the Sun, but it does not reach the distant reaches of the Oort Cloud.
No. The Oort Cloud is "leftover" mass from the formation of the Sun and the planets.
No part of the atmosphere of any planet is any part of the Oort cloud.

Jan Hendrik Oort suggested that comets come from the Oort Cloud. This is sometimes called the Oort Hypothesis.
