2018年12月14日 · The Kuiper Belt is one of the largest structures in our solar system — others being the Oort Cloud, the heliosphere and the magnetosphere of Jupiter. Its overall shape is …

2025年1月2日 · The Kuiper Belt is an enormous, donut-shaped volume of space in the outer solar system. While there are many icy bodies in this region that we broadly refer to as Kuiper Belt Objects (KBOs) or trans-Neptunian objects (TNOs), they're fairly diverse in size, shape, and color.

The Kuiper belt (/ ˈkaɪpər / ⓘ KY-pər) [1] is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at 30 astronomical units (AU) to approximately 50 AU from the Sun. [2] It is similar to the asteroid belt, but is far larger—20 times as wide and 20–200 times as massive. [3][4] Like the asteroid belt, it ...

2025年1月22日 · The Kuiper Belt is a doughnut-shaped region of icy objects beyond the orbit of Neptune. It is home to Pluto and most of the known dwarf planets and some comets.

6 天之前 · Kuiper belt, flat ring of icy small bodies that revolve around the Sun beyond the orbit of the planet Neptune. It comprises hundreds of millions of objects whose orbits lie close to the plane of the solar system.

What is the Kuiper Belt? The Kuiper Belt (sometimes referred to as the Kuiper-Edgeworth Belt) is an area of the outer solar system that is estimated to stretch across 20 astronomical units (AU) of space. It contains small solar system bodies made mostly of ices. The ices are frozen volatiles (gases) such as methane, ammonia, nitrogen and water.

The Kuiper Belt (also known as the Kuiper-Edgeworth Belt) is a disk-shaped region found in the outer solar system, past the orbit of Neptune. It extends from the orbit of Neptune at around 30 Astronomical Units (AU) out to around 50 AU from the Sun and contains hundreds of millions of small icy bodies that are thought to be left over material ...

2023年1月21日 · The Kuiper belt is a thick ring of dwarf planets, comets, and debris out past the orbit of Neptune. The belt contains around one hundred thousand objects that are at least 100 kilometers wide and countless smaller bodies.

2025年1月14日 · What Is the Kuiper Belt? The Short Answer: The Kuiper Belt is a ring of icy bodies just outside of Neptune’s orbit. Pluto is the most famous Kuiper Belt Object. The Sun is at the center of our solar system. It is orbited by eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. But what’s past Neptune?

2023年12月30日 · The Kuiper Belt is commonly defined as the part of the solar system past the orbit of Neptune that is believed to contain numerous comets, asteroids and other small icy bodies.
