Oort cloud facts: the oort cloud is the farthest from the sun that you can go and still be in the solar system it is believed that most comets originate in the oort cloud before falling toward the sun.
The oort cloud the oort cloud is a vast swarm of some 2 trillion comets orbiting our star in the most distant reaches of our solar system, extending from beyond the orbits of neptune and pluto out to 100,000 times the earth-sun distance almost one-third the distance to the nearest star. Abstract we have observed c/2014 s3 (panstarrs), a recently discovered object on a cometary orbit coming from the oort cloud that is physically similar to an inner main belt rocky s-type asteroid. The oort cloud is an immense spherical cloud surrounding the planetary system and extending approximately 3 light years, about 30 trillion kilometers from the sun.
The kuiper belt and even more distant oort cloud are believed to be the home of comets that orbit our sun what is the oort cloud in 1950, dutch astronomer jan oort proposed that certain comets come from a vast, extremely distant, spherical shell of icy bodies surrounding the solar system. The oort cloud is believed to be a thick bubble of icy debris that surrounds our solar system this distant cloud may extend a third of the way from our sun to the next star—between 5,000 and 100,000 astronomical units earth is about one astronomical unit from the sun (roughly 93 million miles or. The outer extent of the oort cloud is believed to be in the region of space where the sun’s gravitational influence is weaker than the influence of nearby stars the oort cloud probably contains 01 to 2 trillion icy bodies in solar orbit.
The oort cloud (/ ɔːr t, ʊər t /), named after the dutch astronomer jan oort, sometimes called the öpik–oort cloud, is a theoretical cloud of predominantly icy planetesimals proposed to surround the sun at distances ranging from 50,000 to 200,000 au (08 to 32 ly.
The kuiper belt is a donut shape aligned with the plane of the solar system the scattered disk is more eccentric and is the source of short period comets and the oort cloud which surrounds the solar system out to great distances is the source of long-period comets. The oort cloud is believed to be a thick bubble of icy debris that surrounds our solar system this distant cloud may extend a third of the way from our sun to the next star—between 5,000 and 100,000 astronomical units.
The oort cloud is 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. The oort cloud is an immense spherical cloud surrounding the planetary system and extending approximately 3 light years, about 30 trillion kilometers from the sunthis vast distance is considered the edge of the sun's orb of physical, gravitational, or dynamical influence.
The oort cloud was named for oort there may be hundreds of billions, even trillions, of icy bodies in the oort cloud every now and then, something disturbs one of these icy worlds and it begins a long fall toward our sun. The cloud is thought to be comprised of two regions – a spherical outer oort cloud of 20,000 – 50,000 au (032 – 079 ly), and disc-shaped inner oort (or hills) cloud of 2,000 – 20,000 au (003 – 032 ly.
