The oort cloud is located outside of our solar system and we say that it was created a long time ago when the planets were still forming. They say that it is the debris left over from it.
It is a cloud of comets and different rocks and particles from way back when.

The Oort cloud, (IPA: BrE /ɔːt klaʊd/, AmE /ɔɹt klaʊd/), alternatively termed the Öpik-Oort Cloud (/'øpik/-, like /'epik/ with a rounded /e/), is a postulated spherical cloud of comets situated about 50,000 to 100,000 AU from the Sun. This is approximately 2000 times the distance from the Sun to Pluto or roughly one light year, almost a quarter of the distance from the Sun to Proxima Centauri, the star nearest the Sun.

The Oort cloud would have its inner disk at the ecliptic from the Kuiper belt. Although no confirmed direct observations have been made of such a cloud, astronomers believe it to be the source of most or all comets entering the inner solar system (some short-period comets may come from the Kuiper belt), based on direct observations of the orbits of comets.

There is also a theory of a denser, inner part of the Oort cloud coined the Hills cloud;[1] it would have a well-defined outer boundary at 20-30 000 AU, a less well defined inner boundary at 50 to 3000 AU, and would be about 10 to 100 times denser than the remainder.[2]

In 1932 Ernst Öpik , an Estonian astronomer, proposed[3] that comets originate in an orbiting cloud situated at the outermost edge of the solar system. In 1950 the idea was revived and proposed[4] by Dutch astronomer Jan Hendrick Oort to explain an apparent contradiction: comets are destroyed by several passes through the inner solar system, yet if the comets we observe had really existed for billions of years (since the generally accepted origin of the solar system), all would have been destroyed by now. According to the hypothesis, the Oort cloud contains millions of comet nuclei, which are stable because the sun's radiation is very weak at their distance. The cloud provides a continual supply of new comets, replacing those that are destroyed. It is believed that if the Oort cloud exists and supplies comets, in order for it to supply the necessary volume of comets, the total mass of comets in the Oort cloud must be many times that of Earth. Estimates range between 5 and 100 Earth masses.

The Oort cloud is located beyond the orbit of Neptune, much farther away from Pluto even. Its distance is about 1 light year from Earth.

The Oort cloud is theorized to be a vast swarm of comets surrounding the Sun in all directions and extending out to very great distances; as much as half way to the next star. It is believed to be left over material from the formation of the solar system. But even with billions of comets, the volume of space is so large that the comets in the cloud would still be hundreds of millions of miles apart! So it is one comet every couple hundred million miles for a couple light years from the Sun outward in all directions.

well, basically, the Oort Cloud is a postulated spherical cloud of comets that is supposedly around 50,000 AU from the Sun (approximately one light year). It provides a continous supply of new comets and it is said that other stars have their own Oort clouds. To read more about it go to the link shown below

The Oort cloud is a sphere of icy bodies and debris that surrounds the solar system, between 50,000 and 100,000 AU from the sun (about 2000 times as far as Pluto or about a light year). It is believed that this sphere is the source of the comets that enter the inner solar system, due to disturbances of their orbits from collisions and from gravitational influences of nearby stars.

The Oort cloud is spherical in shape, hundreds of AU's from the sun, made of leftover material ejected from the solar system disc by the Jovian planets and consists of TRILLIONS of small, comet like bodies. Possibly some of these bodies may be as big as Mars and are so dim are yet to be discovered. Perhaps YOU will discover one!

Would it be a planet if it's as big as Mars but 1000 AU's from the sun and 90 degrees out of the plane???

The Ort cloud is the region--well beyond Neptune's orbit--where it is believed most comets are. The comets we see come from there--but these are only a few of the comets believed t o comprise the Ort cloud. Current models tell us that gravitational interactions between comets occassionaly cause one to shift its orbit and fall inward to the center of the Solar System, close enough for us to see.

Not just beyond Pluto - it is believed to be out to one light year. Pluto is only about 5 light HOURS. So, that gives some idea.
