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).

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 ...
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
The Kuiper belt, scattered disk, and Oort cloud are three conventional divisions of this volume of space. [1] [nb 1] As of February 2024, the catalog of minor planets contains 1060 numbered TNOs. In addition, there are more than 3,500 unnumbered TNOs, which have been observed since 1993. [3] [4] [5] [6]
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 ...
This uncrewed mission flew by Pluto in July 2015. The mission was extended to observe a number of other Kuiper belt objects, including a close flyby of 486958 Arrokoth on New Year's Day, 2019. [68] As of 2011, American scientists are concerned that exploration beyond the Asteroid Belt will hampered by a shortage of Plutonium-238. [needs update]
The total solar eclipse has passed, but there's more to see in the sky. The "devil comet" is passing by and can be seen just after sunset, according to NASA . Here's how you can catch a glimpse.
This was later validated as ‘Kuiper's Belt,’ and despite suggesting it in the 1940s, Edgeworth's astronomical findings were not recognised until 1995. Edgeworth published his autobiography, at age 85, in 1965, Jack of all Trades: The Story of My Life. [9] Kenneth Edgeworth died in Dublin on 10 October 1972, at the age of 92. [25]
