The Grand tack hypothesis explains how in the Solar System giant planets migrated in unique way to form the Solar System belts and near circular orbit of planets around the Sun. [10] [11] [9] The Solar System's belts are one key parameters for a Solar System that can support complex life, as circular orbits are a parameter needed for the ...
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 scattered disc and any potential Hills cloud or Oort cloud objects, are collectively referred to as trans-Neptunian objects (TNOs).

Over one thousand bodies were found in a belt orbiting between about 30-50 AU from the Sun in the twenty years (1992-2012), after finding 1992 QB1 (named in 2018, 15760 Albion), showing a vast belt of bodies more than just Pluto and Albion. [9] [10] By 2018, over 2000 Kuiper belts objects were discovered. [10]
Gerard Peter Kuiper (/ ˈ k aɪ p ər / KY-pər; born Gerrit Pieter Kuiper, Dutch: [ˈɣɛrɪt ˈpitər ˈkœypər]; 7 December 1905 – 23 December 1973) was a Dutch-American astronomer, planetary scientist, selenographer, author and professor. The Kuiper belt is named after him. Kuiper is considered by many to be the father of modern ...
There are about 4,000 known comets in our Solar System so far and most of them come from beyond Pluto, in the Kuiper Belt and Oort Cloud. One of such, called C/2023 A3 Tsuchinshan-ATLAS, will make ...
A 10-million-year integration of the orbit shows that it is a Classical Kuiper belt object that does not get closer to the Sun than 38.8 AU (5.80 billion km) or further than 54 AU. [ 4 ] Physical characteristics
The Kuiper belt, sometimes called the Edgeworth–Kuiper belt, is a region of the Solar System beyond the planets extending from the orbit of Neptune (at 30 AU) [37] to approximately 55 AU from the Sun. [38] It is similar to the asteroid belt, although it is far larger; 20 times as wide and 20–200 times as massive.
A classical Kuiper belt object, also called a cubewano (/ ˌ k juː b iː ˈ w ʌ n oʊ / "QB1-o"), [a] is a low-eccentricity Kuiper belt object (KBO) that orbits beyond Neptune and is not controlled by an orbital resonance with Neptune. Cubewanos have orbits with semi-major axes in the 40–50 AU range and, unlike Pluto, do not cross
