View Full Version : Question on the Oort Cloud

2003-Jun-16, 02:56 PM
First off, hello everyone!

Secondly, I had a question concerning the (as of yet theoretical) Oort Cloud. What is the speculated density of the "giant snowballs" out there? Are they all crowded together like the debris in Saturn's rings, or could you possibly breeze right through without even seeing one, like in the asteroid belt? Or does the density lie somewhere in between these extremes?

I realize it's theory right now, but if anyone has an idea, I'd appreciate it. Thanks! :D

They're fairly sparse. There's a lot of room out there, and the combined mass isn't all that much. I'll leave quantitative answers to someone with more data.

Well, there would be many small sized objects and few large ones, but the Oort cloud is much less dense than the asteroid belt;
there are supposed to be 1,000,000,000,000 (one trillion) comets a kilometer or larger in diameter, each with an average separation of about 1,000,000,000 (one billion) kilometers from its nearest neighbor comet;
that is further than from Earth to Jupiter.
