2025年1月2日 · The Oort Cloud lies far beyond Pluto and the most distant edges of the Kuiper Belt. While the planets of our solar system orbit in a flat plane, the Oort Cloud is believed to be a giant spherical shell surrounding the Sun, planets and Kuiper Belt Objects.

2025年1月2日 · In 1950, astronomer Jan Oort proposed that some comets come from a vast, extremely distant spherical shell of icy bodies surrounding the solar system. This giant swarm of objects, now named the Oort Cloud, occupies space at a distance between 5,000 and 100,000 astronomical units.

2018年12月10日 · Scientific consensus, however, says the solar system goes out to the Oort Cloud, the source of the comets that swing by our sun on long time scales. Beyond the outer edge of the Oort Cloud, the gravity of other stars begins to dominate that of the sun.

2025年1月22日 · Only one spacecraft has visited the Kuiper Belt. NASA’s New Horizons flew past Pluto in July 2015 – sending back the first clear, close-up images of the tiny world.

2017年9月5日 · If you judge by the stopping point of Sun’s gravitational influence, the solar system would end at the Oort Cloud. Transcript. Narrator: Where is the edge of the solar system? The answer is not so simple. You could say it’s where the planets end. But the Sun’s magnetism can be felt far beyond that. And the Sun’s gravity stretches even ...

2022年4月12日 · It is coming from the hypothesized nesting ground of trillions of comets, called the Oort Cloud. The diffuse cloud is thought to have an inner edge at 2,000 to 5,000 times the distance between the Sun and the Earth.

2018年12月10日 · It will take about 300 years for Voyager 2 to reach the inner edge of the Oort Cloud and possibly 30,000 years to fly beyond it. The Voyager probes are powered using heat from the decay of radioactive material, contained in a device called a radioisotope thermal generator ( RTG ).
