Researchers participating in the Discovering the Surface Compositions of Trans-Neptunian Objects program, led by the University of Central Florida (UCF), recently studied these dim objects using ...

Closer To Finding Planet Nine In a paper published in the arXiv physics e-Print server, astronomers found a Trans Neptunian object that is possibly affected by the ninth planet. The object, called ...

“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 [https://iopscience ...

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.

The trans-Neptunian object Arrokoth, also known as Ultima Thule, which NASA's space probe New Horizons passed on New Year's Day 2019, may have changed its shape significantly in the first 100 ...

“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 reveals the binary nature of a trans-Neptunian object (TNO). A new study authored by Southwest Research Institute scientists Rodrigo Leiva and Marc Buie reveals the binary nature of a ...

Astronomers spotted 139 new objects in our solar system in orbit beyond Neptune. Many of these new trans-Neptunian objects reside in the same area of our system that Pluto does, but some are much ...

Data from nearly 60 trans-Neptunian objects helped to identify three “spectral classes” characterizing the spectra they analyzed. Spectral classes are how astronomers categorize stars based on ...

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 ...
