In 2006, Pluto was famously demoted from a planet to a dwarf planet. It remains the most famous dwarf planet today, but there are others in our solar system, including potentially hundreds that ...

Scientists may have discovered a dwarf planet far beyond Neptune — an unearthing that may disprove a longstanding theory about the possibility of a giant ninth planet. The dwarf planet's existence ...

The dwarf planet Ceres is cloaked in a layer of asteroid dust that disguises its true surface composition, a new study suggests. A new color movie combines more than 100 images taken by NASA's New ...

Astronomers have detected the chemical fingerprint of a frozen, water-rich planetary fragment being devoured by a white dwarf star, offering the clearest evidence yet that icy, life-delivering objects ...

Ammonite was discovered using the Subaru Telescope in Hawaii, with follow-up confirmation from the Canada-France-Hawaii Telescope. Its orbit and size officially qualify it as a distant dwarf planet.

The object orbits a brown dwarf that orbits a star, and astronomers aren’t sure if it’s a planet, a moon — or something else ...

In 2020, a study confirmed that two planets orbited the nearby red dwarf, GJ 887. Now, astronomers have confirmed the existence of two additional planets orbiting GJ 887 in a new study published in ...

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 ...

Our solar system is much like a trail of microcosmic breadcrumbs: Follow the molecular bits as far back as they go, and you'll learn a thing or two about where many of our planets and other celestial ...
