How big can planetary systems get?

The video explores the boundaries of the solar system, focusing on the Voyager missions and their journey beyond the heliopause into interstellar space. It explains the concept of the Hill sphere, which defines the true boundary of the solar system, and discusses the influence of nearby stars on this boundary. The video also covers the Oort Cloud, a distant region believed to contain icy bodies and comets. Finally, it speculates on the theoretical limits of solar system sizes, considering massive stars and their gravitational influence.

What are the implications of the Voyager missions in understanding the solar system's boundaries?

What challenges do objects face when orbiting near the boundary of the sun's Hill sphere?

How does the size of a solar system potentially compare to that of a galaxy?
