@interestinghorrorfacts: Voyager 1 took 50 years just to reach a light day (25.9 billion km) meaning radio signals will take a day to reach voyager 1 + another day to come back. But that is just 0.167% of its journey to the end of the solar system, which will take 30000 years (1.6 light years) #crazy #interesting #space #voyager1 #fyp
