@paradoxplanet0: How Long Would Voyager 1 Take to Reach Alpha Centauri? Voyager 1 is hurtling through interstellar space at an astonishing 61,000 km/h (17 km/s). Yet, even at that breakneck speed, reaching Alpha Centauri our closest stellar neighbor would take over 75,000 years. A humbling reminder of just how impossibly vast our universe really is. Would humanity ever build an engine fast enough to bridge the gap? #solarsystem #Astronomy #spacefacts #universe #SpaceExploration
