A newly discovered dwarf planet called 'Ammonite' (2023 KQ14) has been spotted in the outer solar system, and it could be ...

The Kuiper Belt, a vast region beyond Neptune, has long been a source of intrigue for astronomers and space enthusiasts. Known for its collection of icy bodies and dwarf planets, this distant area of ...

NASA launched New Horizons to explore Pluto. In 2019, it visited the furthest object in the Solar System we have seen up ...

The Keck Observatory and NASA’s Hubble Space Telescope may have uncovered a "potential three-body system in the Kuiper Belt," ...

The Kuiper Belt is an elliptical plane in space spanning from 30 to 55 times Earth's distance from the sun, or 2.5 to 4.5 billion miles (4.5 to 7.4 billion kilometers).

Now at 57 AU from the Sun, New Horizons is supposed to have the Kuiper Belt in its rear-view mirror. But its sensors keep detecting dust, an indicator of collisions between objects nearby.

New Horizons will skim just 2,175 miles (3,500 km) above the surface of MU69 on New Year’s Day 2019. Earth-based studies suggest this Kuiper Belt object could be a binary.

The Kuiper Belt is a donut-shaped region of icy bodies beyond the orbit of Neptune. Because small Kuiper Belt objects were some of the "feedstock" from which planets formed, this research provides ...

The Kuiper Belt isn’t just a uniform collection of icy, frozen rocks. Instead, astronomers can detect lots of different colors in the belt’s bodies, including reds, whites, and blues.

The Kuiper Belt is home to Pluto and thousands of other worlds of varying size. Most of the bodies there are made from the building blocks of our solar system, long since cordoned to distant cold ...
