Our Solar System’s Atmosphere We Can’t See: Where’s the Oort Cloud?

Do you know where the solar system ends? If you say Pluto, you are somewhat correct. Pluto is the most distant dwarf planet we have in our country, but scientists understand the limits of the system a little differently.

To be right, our Solar System ends where the Sun’s gravitational effect is too small to capture and hold other cosmic bodies. Of course, the influence of our Sun affects things outside of Pluto’s orbit. The gravity of our sun stops controlling at such a distance From Earth we have no chance of knowing what the edge of our system would look likewrites gate ZME Science.

The boundaries of our system are called a virtual architecture called the Oort cloud. It is believed that this is a kind of ball in which there are countless small ice fragments. There may also be small asteroids in the Oort cloud, but their number will not be large. The Oort cloud is also believed to have formed sometime in the early days of the solar system Due to the attraction of gas giants – Jupiter, Saturn, Neptune and Uranus.

It’s a hypothetical structure, so scientists can’t say for sure whether it exists or not. This is the reason for different estimates of its shape and distance from the sun. Some hypothesize that the Oort cloud begins at a distance of 0.03 to 0.08 light-years from the Sun. On the contrary, some claim that it may be between 1.58 and 3.16 light-years from our star.

“The Oort cloud can be described as a huge, jagged bubble made up of small pieces of ice or other space debris. It is believed that there are billions in this cloud, both trillions of things,” explains the US space agency, NASA.

Structure we can’t see

The Oort cloud is really far away. To give you a better idea of ​​the distance, the perfect example is Voyager 1. It is currently the farthest object we have sent into space, But it won’t reach the Oort cloud in 300 years. It would take her another 30,000 years to cross the cloud. The bad news is that by the time you reach the Oort cloud, Voyager 1 will not be operational.

Oort’s cloud theory dates back to the 1930s. It was first introduced by the Estonian astronomer Ernst Obeck. However, this theory was not recognized until twenty years later. It was also independently designed by Dutch astronomer Jan Oort.

Comets indicate the presence of the Oort cloud. As they approach the sun, they lose ice due to solar radiation. This leads scientists to the idea that they must form far from the star. If true, the situation is also complicated by the gravitational effects of the planets in our system. They claim that a comet must collide with a planet or star or escape the system forever.

However, in our system, we still observe comets orbiting the sun and escaping back to the edge of the system. So scientists believe that there must be a refuge for these things on the very borders. The sanctuary is to be the Oort cloud.
