Our solar system is full of many unknown things, of which we know many things, and some are still unknown, from the planet closest to the Sun and many unknown things to the boundary of the solar system. If we have a spacecraft whose speed is even 10% of that of light, and we go outside the solar system from this spacecraft, then we get to see many things on the way, such as asteroids, comets, Kuiper belt Objects – Rock, metal and all kinds of small and large bodies of ice etc. All the objects present in the solar system are from the time of creation, many of these objects have been formed with the formation of planets, such as asteroids, comets, meteors and meteorites etc., all these objects are in constant motion, because they revolve around the sun, What these objects of the Solar System have always fascinated researchers are.
Those unknown objects, which have fascinated researchers, have made them wonder, why are they different from each other? About 186 billion miles (300 billion kilometers) from the Sun is a group of icy objects known as the Oort Cloud, which orbit the entire Solar System in a plane plane like a planet, the Oort Cloud covers the entire Solar System. It is surrounded by a huge circular circle, about 100,000 AU in width (100,000 times the distance between the Earth and the Sun). Oort cloud is considered to be the last boundary of the solar system, because after this the interstellar starts, if any object or comet from the Oort cloud orbits the Sun, then its orbital period can be thousands or even millions of years, you In this way, we can also understand that when it takes about 30,000 years for NASA’s Voyager 1 to cross the Oort cloud and completely exit our solar system, then what can be the orbital period of a comet.
Most of the objects in the Oort cloud may be made of ice, which can be the size of mountains, because the Oort cloud comes in an area where sunlight has little effect, and here the temperature remains at minus, This is the reason why there are more icy bodies in the Oort cloud. Perhaps sometime in the future, Oort may test the large icy bodies of the cloud, but NASA and other space agencies have a whole flotilla of robotic spacecraft with which to closely explore the smaller worlds that lie within the Solar System.
