Humans explore the vastst expanse of outer space, ultimately hoping to find other habitable, Earth-like planets. These planets may be pregnant with life, and in this way, we can also put an end to the debate about whether humans are alone in the universe. However, sailing to distant star systems means leaving our own solar system in the first place. But where exactly is the boundary between our solar system and interstellar space? Here is Astronomy Online, and today we will answer this particular question: Where is the end of the solar system? Do you love facts? Have you always been curious?
Over the centuries, humans have accumulated a great deal of knowledge about the solar system. We measured the Sun, classified all the planets, mapped their orbits precisely, found moons orbiting them, and even saw pictures of them. Still, there is no consensus on the definition of the solar system, specifically where its boundaries lie. The solar system has no clear edges or boundaries, and deciding on edges or boundaries depends on the criteria we use. Determining a demarcation point is important for dividing the size of the vast solar system and making consistent measurements of the solar system. The problem becomes more difficult because the full picture of the solar system has not yet been fully understood.
The Oort Cloud, the furthest structure around the Sun, contains billions of icy rocks. These rocks occasionally fall toward the sun and become comets. But this is purely hypothetical, because we've never even seen it. Voyager 1 is the most distant spacecraft we have in space, but even it is about 300 years away from reaching the starting point of the Oort Cloud. During this time, both Voyager 1 and 2 encountered structures unknown to scientists. Back in 2007, Voyager 1 encountered a giant foam-like magnetic bubble about 100 million miles wide.
These massive structures, which are about 9 billion miles from Earth, have shocked scientists. They later understood that these bubbles were actually part of the Sun's magnetic field. Due to the rotation of the sun, the outer edge of the magnetic field becomes broken, and there are many nodules and debris. The discovery suggests that there may still be some unknown parts of the solar system.
Still, we have several sets of criteria for determining the end of the solar system. By mass, Neptune, the last planet to orbit the Sun, can be considered an endpoint. While this excludes the Kuiper belt, there is a certain logic. The Sun accounts for 99 percent of all the mass of the solar system itself, with the remaining 1 percent of its mass overwhelmingly coming from Jupiter and gas giants. Relatively speaking, the mass of matter after gas giants can be ignored and can be considered fragments. Carl Sagan once called Neptune "the frontier of the solar system."
From a practical point of view, this is somewhat fascinating, because although there is scientific value in studying asteroids, we are more interested in planets and their moons. However, the removal of the Kuiper Belt from the solar system seems unfounded. Despite its relatively small mass, it is still home to many dwarf planets, including Pluto. Downgrading Pluto from a planet to a dwarf planet is fine, but it seems cruel to remove it completely from the solar system. The Kuiper Belt, home to the last validated satellite to orbit the Sun, is also large — ranging in width from 30 to 50 astronomical units.
One of the astronomical units is approximately the distance between the Sun and the Earth. Many of the more distant comets are from the Kuiper Belt, which may be responsible for the existence of life on Earth in the first place. Life itself may have been sown by a stranded asteroid, and water is thought to have been caused by massively frozen comets and asteroids hitting the Earth's surface. The Kuiper belt is important in isolated systems and should be included. Of course, if we define the solar system as everything captured by the Sun's gravitational pull, we can extend it all the way to the Oort Cloud. The sun's pull, sometimes referred to as the Hiller Roths sphere, is an area of the celestial body where satellites can be captured.
Joining the Ault Cloud will dramatically increase the size of the solar system. The size of the Oort Cloud is unclear, but it is estimated that its outer edge is as many as 200,000 astronomical units from the Sun. It has trillions of celestial bodies, and unlike the Kuiper Belt, it is a cloud, not a belt, and it extends throughout the solar system in a giant bulb. It also provides a convenient cut-off point for the solar system and is the last challenge that travelers who want to leave the solar system must pass.
Outside of the Ault Cloud, there is nothing but gas and dust. Then we can also define the limits of the solar system using the sun's solar layer—placing it between the Kuiper Belt and the Oort Cloud. The heliosphere is a giant bubble of charged particles emitted by the Sun, known as the solar system wind. In 2012, Voyager 1 became the first man-made object to pass through the edges of the heliosphere. The solar constellation, which is about 120 astronomical units away, is the dividing line between the solar wind and the interstellar medium, marking a marked decline in the influence of the Sun.
The news widely reported that Voyager 1 had "left the solar system," though it was still a long way from the Alt Cloud. In 2018, Voyager 2 followed, and they are said to have "left the solar system." So, which definition is correct? The Oort Cloud still exists theoretically, but technically it is more in line with the standard definition of the "solar system."
solar system
The solar system consists of the Sun and small bodies that are attracted to it and revolve around it. NASA's formulation is that the sun and everything in the solar system is bound by gravity. The solar wind top is only the largest range of the Sun's charged particle stream, but it is far from the boundary of the Sun's gravitational pull. There are several different ways to define the extent of the solar system, and determining the exact boundaries depends on what criteria you use.

Are we missing anything?
In the Solar System, the Sun orbits the Sun by gravity or directly or indirectly binding other celestial bodies. The largest objects in the orbit around the Sun are the 8 planets, and the rest are dwarf planets and small bodies and the like. Indirectly orbiting the Sun are the moons of the planets, the two largest of which are larger, one larger than the smallest planet, Mercury, and the other similar to Mercury. 4.6 billion years ago, huge clouds of interstellar molecules collapsed to form the solar system.
Most of the solar system's mass is concentrated in the Sun, and jupiter accounts for most of the remaining mass. The 4 smaller inner circle planets including Mercury, Venus, Earth, Mars belong to the Terrestrial planets and are composed mainly of rock and metal. The four giant exoplanets are much larger than the four little brothers of the Inner Circle System. The two largest planets, Jupiter and Saturn, are made of hydrogen and helium, the outermost Uranus and Neptune are ice giants, composed of water, ammonia, methane, etc., whose melting point is much higher than hydrogen helium, and all 8 planets are almost in a near-circular motion around the sun on the same plane known as the ecliptic plane.
There are also asteroid belts in the solar system between Mars and Jupiter, and most of the small bodies in the asteroid belts are made of rock and metal like terrestrial planets. Beyond Neptune's orbit is the Kuiper Belt, a broken disk-like structure containing a large number of small icy bodies. Further afield is the newly discovered large number of Sedna-like objects. There are some big guys out there that can spin by their own gravity, but exactly how many are still being debated.

The Oort Cloud is a theoretical concept of an icy planetary cloud orbiting the Sun at a distance of 2000 to 200,000 AU (0.03 to 3.2 light-years). Clouds are distributed according to the orbits of long-period comets, and Oort proposes to be 30,000 to 200,000 AU units away from the Sun

Voyager 1 and Voyager 1and 2 Voyager 1 are space probes launched by NASA on September 5, 1977, as part of the Voyager program to study the outer solar system and interstellar space beyond the solar heliosphere. Voyager 2 was launched on August 20, 1977, to study exoplanets and interstellar space beyond the solar heliosphere, and its trajectory would take longer to reach Jupiter and Saturn, but would be able to meet Uranus and Neptune further.
