Here's the breakdown:
* Voyager 1 and 2 are the furthest human-made objects from Earth. They've traveled beyond the heliosphere, the region where the sun's influence dominates.
* The heliopause is the boundary where the solar wind meets interstellar medium. Voyager 1 crossed this boundary in 2012, and Voyager 2 followed in 2018.
* However, the "solar system" is not clearly defined beyond the heliopause. There's a region called the Oort Cloud, a vast shell of icy objects that is thought to extend much further than the heliopause.
* Some scientists argue that the solar system extends to the edge of the Oort Cloud, which is estimated to be about 100,000 AU from the Sun. (1 AU is the distance between the Earth and the Sun).
So, have the Voyagers left the solar system?
* Technically, yes. They have crossed the heliopause and are now in interstellar space.
* But practically, no. They are still within the theoretical boundaries of the Oort Cloud, which is considered part of the solar system by many.
Ultimately, whether you consider the Voyagers to have left the solar system is a matter of definition. The scientific community has not reached a definitive conclusion on the extent of the solar system, and the Voyagers are still providing valuable data about the interstellar medium.
