It's far out, man – literally. Researchers have uncovered the most-distant celestial object in the solar system, a pink dwarf planet nicknamed "Farout," detect at a distance of more than 100 times ...

Fast-moving objects like interstellar comet 3I/ATLAS may be planet-forming seeds, potentially helping to solve an old Solar System mystery. On July 1, 2025, astronomers spotted an object moving ...

There are officially eight planets in our Solar System — yes, I know, Pluto was totally a planet, but not anymore — but that doesn’t mean there isn’t something lurking on the edge of our system that ...

Astronomers have identified the most distant known object in our solar system — a dwarf planet nicknamed Farfarout that orbits far beyond Pluto. This remote mini-planet swings so far away from the sun ...

Astronomers have discovered an object, dubbed “the Goblin,” in the outer reaches of the Solar System. The dwarf planet never gets any closer to the Sun than 6 billion miles, but experts say its ...

Just months after discovering FarOut, the most distant known object in the Solar System, the same team of astronomers has detected the faint—but not yet confirmed—glimmerings of an object even farther ...

A small team led by Sihao Cheng, Martin A. and Helen Chooljian Member in the Institute for Advanced Study's School of Natural Sciences, has discovered an extraordinary trans-Neptunian object (TNO), ...

For a long time, Pluto was the most distant object we knew about in the solar system, but more recent observations suggest there are probably thousands of worlds lurking in the shadows on the fringes.

Astronomers have discovered a new extremely distant object far beyond Pluto with an orbit that supports the presence of an even-farther-out, Super-Earth or larger Planet X. Carnegie's Scott Sheppard ...
