The more we learn, the more we discover how little we really know.
I am going to assume most stars have ort clouds. And passing stars can exchange ort objects as they pass. Pretty cool to think that a comet passing by could have originated from a different star.
An Oort cloud stretching out 3 Light Years surely must mean that it will interact with any similar cloud from Alpha Centauri and its companion stars? They are only 4 light years from here. I'd be interested in what you could find by considering that, Anton.
I was JUST thinking about this today. Like I never thought that the Oort Cloud being spherical made sense due to interstellar perturbations etc.
Thank you, Anton. If the Oort Cloud extends beyond two light years from the sun, a fraction of our cloud would be closer to nearby stars, than the sun. Would that not create havoc as both stars pulled on the cloud? Not to mention whether Proxima Centauri has its own Oort Cloud, which would intermingle with ours!
41 years ago, it was shown that the distribution of aphelion directions of long period comets is not uniform or random on the celestial sphere. Several projects revealed that the Oort cloud was perturbed 2-3 million years ago by a passing star or cloud.
Heeeey! Hello from Estonia! Was nice to hear you mention Öpik
If the Oort cloud is between 2 and 3 years light distance, and this kind of cloud is not exclusive of the Solar System (there is no reason for the opposite), this means that our Oort cloud keeps interacting with the Oort cloud of Alfa or Beta Centauri.
“Strange Pastry” is a great name for a rock band.
Anton: Halley is a short period comet.
