Computer simulations show that planets could be flung out of the inner solar system, supporting the possible existence of a ...

Scientists may have discovered a dwarf planet far beyond Neptune — an unearthing that may disprove a longstanding theory ...

Many people hold Pluto close in their hearts and refuse to abandon the assertion that it is a planet, although science doesn't see it that way.

Space holds endless mysteries, but some images captured by spacecraft and telescopes defy all logical explanations, sparking ...

The discovery of a giant planet orbiting a small red dwarf is challenging the core accretion theory of planet formation. Credit: University of Warwick/Mark Garlick. The discovery of a Saturn-sized ...

However, that doesn’t mean scientists have stopped paying attention to the dwarf planet. New insights and years of data have convinced scientists that Pluto might hide a vast, salty ocean beneath its ...

A possible cousin of Pluto seems to be circling the far reaches of the solar system. The dwarf planet candidate 2017 OF201 travels in a superwide orbit, with the sun relatively near one end of its ...

Yet at the time, he also suggested a way that future astronomers with more powerful equipment could verify if his theory were true by noting that intense mid-infrared radiation should emanate from ...

Some scientists think they discovered a new dwarf planet at the edge of the solar system, so far away that it takes around 25,000 years to complete one orbit around the sun.

“This project was really an adventure.” If confirmed, the newfound dwarf planet would be what Cheng calls an “extreme cousin” of Pluto. The findings were published on the preprint website ...

(Photo: Reuters) advertisement Its size is estimated to be slightly smaller than Ceres—the smallest of the five officially recognized dwarf planets—which measures about 590 miles (950 km) across. For ...

In 2006, updated research led to Pluto being controversially demoted to dwarf planet status by the International Astronomical Union. The reasoning was that Pluto's location in the far-flung Trans ...
