The celestial body's unusual orbit “implies that something extraordinary occurred" in the early days of the solar system—and ...

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 ...

In a groundbreaking discoverypublished in The Planetary Science Journal, a team of astronomers led by the Center for ...

A team of astronomers led by the Center for Astrophysics | Harvard & Smithsonian has discovered a rare object far beyond ...

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.

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.

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 ...

“Stellar Occultation by the Resonant Trans-Neptunian Object (523764) 2014 WC510 Reveals a Close Binary TNO,” Rodrigo Leiva et al., 2020 Sep. 28, Planetary Science Journal ...

The trans-Neptunian region, extending beyond Neptune, represents a primordial reservoir of icy and rocky bodies that have remained relatively unchanged since the Solar System’s formation ...

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.

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.
