An oddly tilted object beyond Neptune moves in perfect sync, one orbit for every ten of Neptune’s, and scientists are ...

The James Webb Space Telescope has observed surface ice methanol — a key building block for organic compounds necessary for life, including sugars — on trans-Neptunian objects.

Of the 461 objects described for the first time in the new paper, a few stand out. Nine are known as extreme trans-Neptunian objects, which have orbits that swing out at least 150 AUs from the sun.

Harvard & Smithsonian have discovered a rare trans-Neptunian object, 2020 VN40, orbiting in perfect sync with Neptune.

“These objects would escape from the Solar System in less than 1.5 billion years, -he adds-, and in the case of 2004 VN112, 2007 TG422 and 2013 RF98 they could abandon it in less than 300 ...

A new study from researchers at the Southwest Research Institute has unearthed a fascinating discovery about Arrokoth, a trans-Neptunian object made famous by the New Horizons probe in 2020.

Nine are known as extreme trans-Neptunian objects, which have orbits that swing out at least 150 AUs from the sun. Four of those are extremely extreme, with orbital distances of 230 AUs.
