The Oort cloud, sometimes called the Öpik–Oort cloud, is theorized to be a cloud of billions of icy planetesimals surrounding the Sun at distances ranging from 2,000 to 200,000 AU. Its existence was p
Kuiper belt
…objects such as Eris have extremely eccentric orbits that take them as far as 100 AU from the Sun. The Kuiper belt is distinct from the hypothesized Oort cloud, which is believed to be a thousand times more distant and mostly spherical. The objects within the Kuiper belt, together with the members of the…

The distance from the Oort cloud to the interior of the Solar System, and two of the nearest stars, is measured in astronomical units. The scale is logarithmic: each indicated distance is ten times as far out as the previous distance. The red arrow indicates the projected location, in 2025–2027, of the space probe Voyager 1, which may reach the Oort cloud about 300 years later.
