Kuiper Belt
Wealth of information about Kuiper Belt Objects, including ephemerides for those who would like to observer them along with a number of movies and images.

New Horizons: NASA's Pluto/Kuiper Belt Mission
News about Pluto and the Pluto/Kuiper Belt mission that will fly by Pluto in 2015.

Distant EKOs
The Distant EKOs Newsletter is dedicated to the dissemination of research relevant to the Kuiper belt. The goal is to provide researchers with easy and rapid access to current observational and theoretical studies of the Kuiper belt, directly related objects (e.g., Pluto, Centaurs), and other areas of research that are explicitly applied to the Kuiper belt.

A Deep Ecliptic Survey for Kuiper Belt Objects
Astronomers are using the KPNO Mosaic camera with the Mayall 4-metre telescope to identify Kuiper Belt Objects (KBOs, also known as Trans-Neptunian Objects). The goals of their survey are to answer several fundamental scientific questions.

What We Know About Pluto, Charon and the Kuiper Belt
NASA site providing inforamtion on what's currently known about Kuiper Belt Objects.

Kuiper Belt Movie
Lynne Allen and Gary Bernstein, formerly of the UM Astronomy Department, observed several square degrees of the sky in order to discover very faint KBOs, in an effort to learn more about the formation of the Solar System. This movie shows the appearance of a small patch of the sky observed over 2 nights in May, 1998 as part of this project.

Moons Over the Kuiper Belt
In the not-too-distant past, the planet Pluto was thought to be an odd bird in the outer reaches of the solar system because it has a moon, Charon, that was formed much like Earth's own moon was formed. But Pluto is getting a lot of company these days. Of the four largest objects in the Kuiper belt, three have one or more moons.

Frequently Asked Questions About Quaoar
Quaoar is a newly discovered Kuiper Belt object, found in June 2002 by Chad Trujillo and Mike Brown at Caltech in Pasadena. It's half the diameter of Pluto (about 1/8 the volume), and 1.6 billion kilometers (1 billion miles) further away than Pluto.

Frequently Asked Questions About 2004 DW
2004 DW is a newly discovered Kuiper belt object, found in images taken Feb 17 2004 (nearly 74 years to the day after Pluto was discovered). 2004 DW is one of the largest Kuiper Belt objects currently known. Initial indications are that it may be over half the diameter of Pluto, larger than Quaoar, and 2.4 billion kilometers (1.5 billion miles) further away than Pluto.

The discovery of 2003 UB313, the 10th planet
The new planet, colloquially named 'Xena', is the most distant object ever seen in orbit around the sun, even more distant than Sedna, the planetoid discovered almost 2 years ago. It is almost 10 billion miles from the sun and more than 3 times more distant than the next closest planet, Pluto and takes more than twice as long to orbit the sun as Pluto.

Sedna
Sedna is the coldest most distant place known in the solar system; possibly the first object in the long-hypothesized Oort cloud.

List Of Transneptunian Objects
This list is updated daily, except for the few days surrounding the preparation of each batch of MPCs. It is also updated as and when new objects are discovered.

The Edge of the Solar System
An account of a detection experiment to locate Kuiper Belt objects along the ecliptic. No objects were found beyond 65AU.
