Answer 1

Answer:

Explanation:

he Oorta Cloud is a hypothetical region of the solar system that serves as the source of comets with a long period of revolution. Instrumental existence of the Oort cloud is not confirmed, but many indirect facts indicate its existence. The estimated distance to the Oort cloud from the Sun is from 50,000 to 100,000 a. e. - almost a light year. The idea of ​​the existence of such a cloud was first put forward by the Estonian astronomer Ernst Epic in 1932, and then theoretically developed by the Dutch astrophysicist Jan Oort in the 1950s, after whom the cloud was named. Some astronomers consider Sedna to be the object of the inside of the Oort cloud.

On August 18, 2008, at the conference “Sloan Digital Sky Survey: Asteroids in Cosmology”, University of Washington astronomers provided evidence of the origin of the Trans-Neptune Object 2006 SQ372 from the Oort Olabco Oort cloud consists of billions of ice bodies. Occasionally passing stars violate the orbit of one of the bodies, causing it to move into the inner part of the solar system as a long-period comet. Such comets have a very large and elongated orbit and, as a rule, are observed only once. One example of long-period comets are comets Halley and Swift.
