Where Does The Solar System End

The boundary of the solar system is not precisely defined. Traditionally, it extends to the heliopause, where the solar wind meets the interstellar medium. Voyager 1, launched in 1977, is now in interstellar space, marking a distant boundary. However, the Oort Cloud, a vast region of icy bodies, is believed to be the outermost extent, making the solar system's true end challenging to pinpoint.
