Does the Oort cloud have any large holes in it and if not does this . . . The Oort cloud (assuming it exists) is made up of many small objects in orbits in a wide range of orientation, distance, and eccentricity What that means is the orbital period of any given two objects are almost certain to be wildly different, and their paths crisscross throughout the cloud
Whats the reason for the hollow region in Oort cloud? The Oort cloud itself is thought to be mainly populated with objects that formed in the inner Solar System, where the protostellar disc was dense Small asteroids that are close to the giant planets can pick up a series of orbital perturbations that boost their eccentricity and semi-major axis, whilst keeping their perihelion distance roughly
What are the relative distances between objects in the Oort cloud? The Oort Cloud has many more objects than the main asteroid belt, some trillion objects larger than a kilometer, but it also occupies a much larger volume of space from 5,000 AU to beyond 20,000 to 50,000 AU from the Sun Oort Cloud objects larger than 1 km have some 31 million miles (50 million km) between each other
Do other stars have Oort clouds? - Astronomy Stack Exchange If they have Oort clouds, would there not be interactions between their Oort cloud objects and the planets of the Solar system? For example, the outer edge of the Sun's Oort cloud is approximately 100,000 AU away So, if another star comes at a distance of 1 light year from the Sun, its Oort cloud should similarly go through the inner solar system
Do all stars have an Oort cloud or is it a rare occurence? 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 And objects in Oort Clouds around other stars would appear even fainter
Are solar systems formed from a gas centrifuge? The Oort cloud was not formed where it is now Oort cloud objects were formed much closer to the Sun, within the planetary system and then scattered outwards by gravitational interactions with the giant planets
Why is the Oort cloud presumed to be spherical? The Oort cloud objects are thought to be the reservoir of very long period cometary bodies They are inferred to have a spherical distribution because the very long period comets that enter the inner Solar System do so from random directions
Newest oort-cloud Questions - Astronomy Stack Exchange The Oort cloud is a hypothetical structure based on our observation of long-period comets There are currently proposals to design probes to confirm the existence of the Oort cloud
orbit - Why didnt passing stars destroy the Oort cloud? - Astronomy . . . The Oort cloud is disturbed This is thought to be one of the ways we can get long period comets It is also depleted of objects over time and it is likely that only a fraction of the original objects in the cloud remaining I guess what you really mean is why isn't the Oort cloud completely removed on a short timescale? The reason is that not only does an interloper have to get close enough
