The Kuiper belt as a research area encompasses the systematic investigation of the trans-Neptunian region of the Solar System populated by icy planetesimals, dwarf planets, and small bodies beyond Neptune’s orbit. Research focuses on the dynamical structure, composition, and collisional evolution of Kuiper belt objects (KBOs) to constrain models of planetary formation, migration, and early Solar System architecture. This field integrates observational surveys, orbital dynamics, spectroscopy, and thermophysical modeling to characterize size distributions, surface and volatile properties, and resonant populations, and to understand the Kuiper belt’s role as a reservoir for short-period comets and as a probe of primordial circumstellar disk conditions.
A vast region of our solar system, called the Kuiper belt, stretches from the orbit of Neptune out to 50 or so astronomical units (AU), where an AU is the distance between Earth and the sun. This region consists mostly of ...
Astronomers have discovered what they think may be another moon orbiting a distant dwarf planet called Quaoar. This small, icy, egg-shaped planet in the far reaches of our solar system, beyond Neptune, is already known to ...
Trans-Neptunian objects (TNO) are some of our solar system's lesser-known objects. They number in the thousands, and they get their name from their orbits. These dwarf planets orbit the sun at a greater average distance than ...

As NASA's New Horizons spacecraft traveled through the Kuiper Belt at a distance of more than 5.5 billion miles from Earth, an international team of astronomers used the far-flung probe to conduct an unprecedented experiment: ...
The first observations of Pluto by NASA's James Webb Space Telescope (JWST) reveal dramatic phenomena on its surface, like seasonal cycles of volatile ice redistribution across its surface, and material being pulled from ...
