@astr.o_venus: Most people think the Solar System ends somewhere around Neptune. But neyond Neptune lies the Kuiper Belt, home to Pluto, Sedna, and thousands of frozen world. But even that isn't the end, far beyond at the edge of our Sun's gravitational reach, lies the Oort Cloud a vast shell of icy bodies stretching up to ~ 3.2 light-years from the Sun. Voyager 1, the fastest object humanity has ever launched, has been traveling since 1977 and it will take approximately 30,000 years to fully pass through it. #voyager1 #space #immensity #Astronomy #solarsystem
