The Oort cloud is a shell of icy bodies that surrounds the solar system. ... Most objects that orbit the sun orbit on the same plane, like the planets, the asteroid belt and the Kuiper Belt.

It's the Oort Cloud, named after Jan Hendrik Oort. Unlike our local asteroid belt, and the more distant Kuiper Belt, which form orbiting bands, this is an enormous spherical cloud.

Astronomers have discovered a rare instance of a interstellar comet speeding through the solar system. The 3I/ATLAS was first ...

Creating Comets. The Oort cloud spans a great distance, from around 2,000 to between 100,000 and 200,000 astronomical units ...

That truth, as we all know, is that a large, undetermined and (for good reason) indeterminable fraction of the bodies in the asteroid belt, the Kuiper Belt and the Oort Cloud are the sites of ...

Previously, comets were understood to originate from the Kuiper Belt and Oort Cloud, which both sit beyond Neptune's orbit, and the distance away from the Sun would help preserve ice on the comets ...

They're part of a new class of asteroid belt objects that, unlike asteroids, show a comet-like halo and tail. Photo: NASA/ESA/CSA/J. Olmsted/M. Kelley Among the first such objects to be discovered ...

Despite the difficulty, astronomers have been searching the Oort cloud (and the nearer Kuiper Belt) for decades, in the hopes of finding the elusive “hypothetical Planet X.” ...

From the icy comets that journey through the outer reaches to the rocky asteroids that populate the asteroid belt, ... The existence of the Oort Cloud was proposed by Jan Oort in 1950.
