The Kuiper Belt is shown beyond the orbit of Neptune. One of its inhabitants is Eris, on a highly tilted and elliptical orbit. (Image credit: NASA) Who discovered the Kuiper Belt?

For Amazon, Project Kuiper is a long-term, high-stakes bet on India’s satellite broadband future. While competitors like ...

For years, scientists have been scanning the icy outskirts of our Solar System for an unknown massive planet. The ...

The result, today, is that the largest and most massive body ever to form in the Kuiper belt — 20% larger than Pluto; 29% more massive than Eris — is now Neptune's largest moon: Triton.

On New Year’s Day of 2019, when the spacecraft was almost 1.5 billion kilometers beyond Pluto’s orbit, it flew past another Kuiper Belt object. And what a surprise it was.

Amazon's next group of Kuiper satellites could soon reach orbit, propelling the company closer to providing internet to ...

We determined that an Earth-like planet (m ∼ 1.5–3 M⊕) located on a distant (semimajor axis a ∼ 250–500 au, perihelion q ∼ 200 au) and inclined (i ∼ 30°) orbit can explain three fundamental properties ...

Here we report that the Kuiper-belt object 1998 WW31 is binary with a highly eccentric orbit (eccentricity e ≈ 0.8) and a long period (about 570 days), very different from the Pluto/Charon ...

At one point in its orbit it would travel through the Oort cloud disturbing the orbits of the objects there and sending lots of them ... Most of the Kuiper Belt was probably perturbed outward ...
