NASA's New Horizons spacecraft flew past Ultima Thule in the early hours of New Year's Day, ushering in the era of exploration from the enigmatic Kuiper Belt.
The wonders – and mysteries – of Kuiper Belt object 2014 MU69 continue to multiply as NASA's New Horizons spacecraft beams home new images. In 1951 he had the idea that a belt of icy bodies might have existed beyond Neptune when the solar system formed. In the doughnut-shaped region of space beyond Neptune, the outer edges of our solar system, called the Kuiper Belt. The Kuiper Belt extends from roughly the orbit of Neptune (at 30 AU out to about 55 astronomical units from the Sun. It’s the most famous of the objects floating in the Kuiper Belt, which are also called Kuiper Belt Objects, or KBOs. Explore the Kuiper Belt In Depth ›. There may be hundreds of thousands of icy bodies larger than 100 km (62 miles) and an estimated trillion or more comets within the Kuiper Belt. With no apparent hazards in its way, NASA's New Horizons spacecraft has been given a "go" to stay on its optimal path as it speeds closer to a Jan. 1 flyby of a Kuiper Belt object a billion miles beyond Pluto. A classical Kuiper belt object, also called a cubewano , is a low-eccentricity Kuiper belt object (KBO) that orbits beyond Neptune and is not controlled by an orbital resonance with Neptune. The Kuiper Belt is named after a scientist named Gerard Kuiper.
It’s primarily made up of icy objects, dwarf planets, dust, and comets. It’s called New Horizons and will survey Pluto. Putting together the data to officially recognize it and its components took many scientists many years. Egg-shaped Haumea has a ring around it.
Kuiper Belt vs Oort Cloud.
It contains small solar system bodies made mostly of ices. The Kuiper Belt is a ring of icy bodies just outside of Neptune’s orbit. Given their frequent trips into the inner solar system, most tend to exhaust their volatile ices fairly quickly and eventually become dormant, or dead, comets with little or no detectable activity.Researchers have found that some near-Earth asteroids are actually burned-out comets, and most of them would have started out in the Kuiper Belt.
Similar to the asteroid belt, the Kuiper Belt is a region of leftovers from the solar system's early history. Kuiper Belt is a donut-shaped region of icy bodies beyond Neptune’s orbit. It's a place we've only just begun to explore, but it holds important clues to the origins of our solar system. The Kuiper Belt shouldn't be confused with the Oort Cloud, which is a much more distant region of icy, comet-like bodies that surrounds the solar system, including the Kuiper Belt. Director, NASA Planetary Science Division:
Another common question people ask about the Kuiper belt is what’s exactly out there! There may be millions of these icy objects, collectively referred to as Kuiper Belt objects (KBOs) or trans-Neptunian objects (TNOs), in this distant region of our solar system.
10 Need-to-Know Things About the Kuiper Belt Astronomers think the icy objects of the Kuiper Belt are remnants left over from the formation of the solar system. The inner edge of the Kuiper Belt begins at the orbit of Neptune, at about 30 AU from the Sun.
The ices are frozen volatiles (gases) such as methane, ammonia, nitrogen and water. The New Horizons spacecraft flew past the ancient Kuiper Belt object Arrokoth (2014 MU69) on Jan. 1, 2019, providing humankind’s first close-up look at one of the icy remnants of solar system formation.
Its overall shape is like a puffed-up disk, or donut.
Astronomers are searching for a possible planet that might explain the strange orbits of several Kuiper Belt Objects. The inner edge begins at the orbit of Neptune, at about 30 AU from the Sun. According to NASA, there are more than a trillion comets out there in the Kuiper belt. Where do the icy bodies and other leftovers from our solar system collect?
Astronomers have found structures similar to our Kuiper Belt around at least nine other stars. There may be hundreds of thousands of icy bodies larger than 100 km (62 miles) and an estimated trillion or more comets within the Kuiper Belt. It is not clear if worlds in this distant, cold region are not capable of supporting life as we know it.
It’s likely in the not too distant future that we’ll see many more dwarf planets added to the list. Kuiper belt [ kī ′pər ] A disk-shaped region in the outer solar system lying beyond the orbit of Neptune and extending to a distance of about 50 astronomical units, containing thousands of small, icy celestial bodies. After this in 1992, thousands more KBO’s have been found. As well as this, there’s actually supposedly more than 100,000 different objects out there that are larger than 100km!
It’s where four of the five dwarf planets reside, and a whole lot else is out there too. It’s where four of the five dwarf planets reside, and a whole lot else is out there too. 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. Even though there are tons of objects out there, we don’t think that they total up to any more than 10% of the Earth’s mass. New Horizons is slated to fly past another KBO—2014 MU69 (nicknamed "Ultima Thule" by the mission) on New Year's Eve 2018.
Short-period comets (which take less than 200 years to orbit the Sun) originate in the Kuiper Belt.
A fairly large number of KBOs either have moons—that is, significantly smaller bodies that orbit them—or are binary objects. If it took a decade to make it there at this speed, imagine how long it would take for a human to travel this far at normal speeds!
But what’s past Neptune? Credit: NASA. Kuiper Belt specializes in a wide range of high-quality and innovative support services industries.
NASA Official: So far, over 2,000 KBOs have been cataloged.
Objects there occasionally collide, with the collisional fragments producing smaller KBOs (some of which may become comets), as well as dust that's blown out of the solar system by the solar wind. So sometimes you’ll see objects there referred to as KBOs (Kuiper Belt Objects) or TNOs (. Closest approach takes place in the early morning hours of New Year's Day—12:33 a.m. EST—marking the most distant close exploration of worlds ever completed by humankind.
Several similar-sized objects were discovered quickly confirming the Kuiper belt was real. Go farther. Although we knew that the Kuiper was probably out there in the 1950s, it was until 40 years later that we actually found the first KBO.
These are called short-period Jupiter-family comets. The best information has come from recent missions, so there is much to discover and learn. The Kuiper belt remained theory until the 1992 detection of a 150-mile wide body, called 1992QB1 at the distance of the suspected belt.
Astronomers think that these are essentially the leftovers and remains of the formation of our solar system. The Kuiper Belt is named for astronomer Gerard Kuiper, who published a scientific paper in 1951 that speculated about objects beyond Pluto.
Cubewanos have orbits with semi-major axes in the 40–50 AU range and, unlike Pluto, do not cross Neptune's orbit.
5 Where do comets come from? I also have some cool facts to share with you too, so let’s get started! Instead, Neptune’s gravity stirred up this region of space so much that the small, icy objects there weren’t able to coalesce into a large planet.
The New Horizons mission from Earth to Pluto took 9.5 years for it to make it there – that’s how long it took to get to the Kuiper belt from Earth! Like the asteroid belt, it contains millions of small bodies, all remnants from the Solar System’s formation. Bill Dunford, This site is maintained by the Planetary Science Communications team at, The main part of the Kuiper Belt begins at Neptune's orbit. 4
The Kuiper Belt is a region of space. There are hundreds of millions of icy objects out in the Kuiper belt. Another interesting Kuiper Belt Object is Haumea.
The amount of material in the Kuiper Belt today might be just a small fraction of what was originally there.
Cosmic Doughnut Several similar-sized objects were discovered quickly confirming the Kuiper belt was real.
He’s a big part of why we know what we do today, and he knew what the moon would feel like before we even went there! The first spacecraft to enter the Kuiper Belt region was NASA’s Pioneer 10 spacecraft, when it crossed into the space beyond Neptune’s orbit in 1983.

The Kuiper Belt is a doughnut-shaped ring of icy objects around the Sun, extending just beyond the orbit of Neptune from about 30 to 55 AU.
