If the Oort Cloud is three light years away from our Sun, then it's closer to Alpha Centauri than our Sun, right? So how can it stay around our Sun if the mass of Alpha Centauri is 1.1 times the mass ...
Right now we can’t observe extrasolar Oort clouds, if they exist. (Not for lack of trying; we’ve been looking for them since 1991!) In fact, we can’t even directly observe our own Oort Cloud. We can ...
The Oort Cloud, an expanse of icy bodies in the far reaches of our solar system, is shown here in a scene from "Encounters in the Milky Way," a show at New York City's Hayden Planetarium that spawned ...
It almost sounds like a riddle. We know where comets come from, even though we've never seen their home. Some comets come back into the inner solar system again and again every few decades. But some ...

A thick sphere of icy debris known as the Oort cloud shrouds the solar system. Other star systems may harbor similar icy reservoirs, and those clouds may be visible in the universe’s oldest light, ...
The human mind may find it difficult to conceptualize a cosmic cloud so colossal it surrounds the Sun and eight planets as it extends trillions of miles into deep space. The spherical shell known as ...
The Oort cloud is a region in our solar system's vicinity we don’t know all that much about. Named after Dutch astronomer Jan Oort, it is a theoretical concept comprising planetesimals (solid objects ...
