Web11 de dez. de 2024 · If you placed Voyager 1 in the Oort cloud right now, it'd be difficult to contact it (but maybe not impossible). We can barely communicate with the Voyagers now at ~140 AU using a 70 m DSN antenna. The DSN can use the VLA (one of the largest radio telescopes on Earth), that may provide enough aperture to receive the Voyagers.
WebA) The original solar nebula happened to be disk-shaped by chance. B) Any planets that once orbited in the opposite direction or a different plane were ejected from the solar system. C) The laws of conservation of energy and conservation of angular momentum ensure that any rotating, collapsing cloud will end up as a spinning disk. D) The Sun ... WebOort Cloud. In 1950, Jan Hendrik Oort (1900-1992) inferred the existence of the Oort Cloud from the physical evidence of long-period comets entering the planetary system. As Ernst Julius Öpik (1893-1985) also may have speculated about such a reservoir of cometary bodies as early as 1932 as the source of long-period comets, it is also called ...
