The article explores whether large planets exist in the Kuiper belt. It describes Kuiper belt as a region of icy bodies beyond Neptune that measures at least several thousands astronomical units (a.u....
Kuiper Belt: The Kuiper belt is an area of space just beyond the orbit of Neptune. It is rich with objects and is considered a reservoir of short-period comets. The belt extends approximately 20 astronomical units from its inner boundary to its outer boundary. ...
The planets' sizes and orbits distinguish them from asteroids, comets, and meteoroids, as well as icy objects beyond Neptune in the Kuiper Belt, like the dwarf planet Pluto. Each one is iconic in its own way, but as is the way of the universe, only one can be the best. Judged by ...
The other reservoir, the Kuiper belt, is a thick disk-shaped zone whose main concentration extends 30–50 AU from the Sun, beyond the orbit of Neptune but including a portion of the orbit of Pluto. (One astronomical unit is the average distance from Earth to the Sun—about 150 million ...
"Lives of the Planets" is a sweeping tour of our solar system, from the sun and demoted Pluto, to the Kuiper Belt and beyond the edge of the interstellar void. From the Neolithic computer that is Stonehenge to Galileo's telescope to Kepler's latest search for life on other planets, Rich...
in the area surrounding the solar system, in the far reaches of the swarm of comets known as the Oort cloud or in the disk of debris known as the Kuiper belt. All of these objects travel around the sun at high speeds in paths called orbits. Some of these orbits, like those of the...
an object in the Kuiper belt beyond Pluto. At the same meeting, the IAU created a third category of objects known assmall solar system bodies,which includes asteroids (sometimes referred to as "minor planets," compounding the difficulty of the termplanet), comets, objects beyond Neptune's orbi...
A little over 10 years ago, our perception of the Solar System changed drastically with the discovery of the first Kuiper belt object. As the number of known objects increased (it is now well over 500), a picture has emerged which shows a Kuiper belt with two major components: a cold po...
Now, a pair of astronomers from the California Institute of Technology think they have evidence that will restore the sun's record to its previous value. Their analysis of objects orbiting in the Kuiper Belt(柯伊伯带), a ring of frozen asteroids(小行星)that circle beyond the orbit of Neptun...
Kuiper Belt The Kuiper Belt Awards Philip Metzger,May 1, 2015 Note: this post (with the previous one) is intended to illustrate how BIG our solar system is by reviewing all the named bodies beyond Neptune. When Pluto was reclassified as ‘not-a-planet’ then people interpreted it to mean...
