Do Oort clouds exist in other solar systems too?

Oort-cloud objects are 2,000 - 50,000 (or more) AU away-- so these objects, to us in the same solar system, have an apparent magnitude much fainter than 11. The point of that poorly-explained interlude is that these objects are faint. Very faint. read more

The point of that poorly-explained interlude is that these objects are faint. Very faint. And objects in Oort Clouds around other stars would appear even fainter. read more
